Yes, that is often possible. It depends on the equation, of course - some equations have no solutions.

Can you solve for a variable in an equation?

Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.

What number when substituded for the variable in an equation makes the equation true?

you have to solve the actual equation in order to answer this about your variable

Can you solve for a variable in an expression?

No, you can only simplify an expression. To solve for a variable, it must be in an equation.

Can you solve for a variable in an expression or equation?

you can only solve for one in an equation so it can equal something

Can you solve a variable with an equation?

When an equation has a variable in it (only one), then there are only certainvalues the variable can have that will make the equation a true statement."Solving" the equation means finding those values for the variable.

What does SOLVE stand for in math?

"Solve an equation" means "find out, for which values of the variable or variables is the equation true".

What does solve the equation mean?

Find values for the variable that satisfy the equation, that is if you replace those values for the variable into the original equation, the equation becomes a true statement.

How do you solve an equation with a variable that is a fraction?

You solve the equation the same way as you would any other equation. Whether the variable is a fraction or otherwise will only become clear once you solve the equation. In other words, you don't initially KNOW whether the solution will be a fraction or not.

How can you find a variable in math?

You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables. Then you solve the equation(s), using algebra.You find, or construct, an equation or set of equations which express the unknown variable in terms of other variables.

How does writing equivalent equations help you solve a system of equations?

You can write an equivalent equation from a selected equation in the system of equations to isolate a variable. You can then take that variable and substitute it into the other equations. Then you will have a system of equations with one less equation and one less variable and it will be simpler to solve.

How do you solve word problems using variables?

Use a variable to represent the unknown. 'Translate' the words to math symbols and write an equation to solve. Solve the equation. Check.

How do you solve for the indicated variable?

Algebraically manipulate the equation until you have the indicated variable on one side of the equation and all of the other factors on the other side.

What is an equation with one or two variables?

When you solve a one-variable equation, your goal is to isolate the variable.To isolate the variable means to make it be alone on one side of the equals sign.In the equation shown here, you can isolate the variable by subtracting 9 from both sides of the equation and simplifying

How doI solve system of equations by substitution?

Assuming the simplest case of two equations in two variable: solve one of the equations for one of the variables. Substitute the value found for the variable in all places in which the variable appears in the second equation. Solve the resulting equation. This will give you the value of one of the variables. Finally, replace this value in one of the original equations, and solve, to find the other variable.

What do you do when you have a negative variable?

When you have a negative variable in an equation that you are trying to solve for, you multiply each side of the equation by -1. If it is an inequality such as <, you would flip the sign to > and vice versa.

How do you solve a equation using unknown variables?

You don't use unknown variables to solve an equation. The purpose of solving an equation is to find the value of the variable so that it's no longer unknown.

What is the math term VEST?

variable equation solve it test it

Which is the best way to solve the equation the square root of x equals m?

It depends on which variable you wish to solve for.

How do you solve log sub 9 parenthesis a over 27 closed parenthesis equals x minus 2?

Your equation has two variables in it ... 'a' and 'x'. So the solution is a four-step process: 1). Get another independent equation that relates the same two variables. 2). Solve one of the equations for one of the variables. 3). Substitute that into the other equation, yielding an equation in a single variable. Solve that one for the single variable. 4). Substitute that value back into the first equation, and solve it for the second variable.

Can you solve an variable in an equation?

You may want to be a little more specific about what your question is asking....... you can solve a variable in an equation or expression. For example: 1+2=y just remember, you arnt necessarily "solving" a variable, but I guess you could say that considering a variable can change continuously. Be sure to consider that if you do "solve" a variable you end up with a constant ( a never-changing number) therefore, it is no longer a variable, but just an answer. Hope that helped! :-)

How do solve for the variable over a number in a linear equation?

Well a variable in a number in a linear equation is basically the variable divided by a number. So if you have x over 10, it is basically x times 1/10. You can solve by having either another equation and use either point slope or y=mx+b.

How do you easily balance and solve a scientific equation?

A scientific equation is basically a math equation. Those come in different kinds; each kind needs special techniques for solving. In the simplest case, you have to solve for a single variable; try to transform the equation so that your variable is on the left, and anything else is on the right.

When using the substitution to solve nonlinear system of equations you should first see if you can one variable if you can one variable in one of the equation in the system?

The general idea is to solve one of the equations for one variable - in terms of the other variable or variables. Then you can substitute the entire expression into another equation or other equations; as a result, if it works you should end up having one less equation, with one less variable.

How do you solve the equation 720 equals 2a x 3b x 5c?

I have the feeling that you were looking to find a value for each variable in this equation. Unfortunately you can only solve for each variable in terms of the other variables in this equation.
