Substitute the value found back into the equation, evaluate the expressions and see if the resulting equation is true.

You replace the variable by the purported solution, and do all the calculations. If you end up with a true statement, for example 5 = 5, then it is a solution.

Substitute the number in place of the variable. Evaluate the expressions. If the resulting equation is true then the number is a solution.

if you plug the solution back into the equation both sides of the equation will be equal

Using the Kw equation how is it possible to determine whether an aqueous solution is acidic basic or neutral?
When you combine the Kw equation with the total mass of the solution, you will get a number. If the number is above 60, it is a acid, it is below 75, it is a base and if your number is between 60 and 75, it is neutral.
A is a number that makes an equation true.?
If A is a number that makes an equation true, then A is a "solution" to the equation.
A value that makes an equation true?
Any number that makes an equation true is a 'solution of an equation'. it is a solution
What does it mean when it says determine whether the given value of the variable is a solution?
I'm going to assume you have an equation to go with your variable? It means "Check if this number works" What to do is put the given value into the equation instead of the variable and see if the result is true - if it is you have a solution, if not you don't. I'll make one up as a demo: Equation : a + 4 = 7 is a = 2 a solution? a+4=7 2+4=7 6=7 (FALSE!) No this given value is not a solution.
Number that makes an equation true?
A number that makes an equation true is its solution.
What is the word for a number that makes an equation true?
Solution. A solution of an equation is a number that satisfy the equation. This means that if you replace this number on the equation and check it, the equation will be true. When you solve an equation you can find some roots, but not all of them satisfy the equation. Thus always check your answers after resolving your equation, and eliminate as solution the answers that don't make the equation true or undefined.
Math tell whether the ordered pair is a solution of the equation?
The idea is to replace one variable in the equation by the first number in the ordered pair, the other variable with the second number in the ordered pair, do the calculations, and see whether the resulting expressions are indeed equal.
When can you say that a number is called a solution in algebraic expression?
An algebraic equation or inequality can have a solution, an algebraic expression cannot. If substituting a number in place of a variable results in the equation or inequality being a true statement, then that number is a solution of the equation or inequality.
What is a number that makes the equation true?
The solution (or solution set, if more than one number).
What is the number that makes an equation true called?
It's callled the "solution" of the equation.
A is a number that makes an equation true?
The solution set is the answers that make an equation true. So I would call it the solution.
Which equation has solution x -3?
The equation that has the solution x = -3, is, precisely:x = -3 If you want anything more fancy, you can add some number (the same number to both sides), multiply by some number (the same number to both sides), etc.
A number that produces a true statement when substituted?
I assume you mean, in an equation. Such a number is called a "solution" or a "root" of the equation.
What is an infinite solution to an equation?
An infinite solution means that are an infinite number of values that are solutions.
A number that makes a equation true?
A number that makes an equation true is a solution. If there is more than one answer to an equation (such as an equation like): (x-2)(x+4)=0 then it is called a solution set (and in this case would be x={-4, 2}).
How do you know when a number is not a solution of an equation?
When you put the number in place of the variable (like maybe the 'x' or the 'y') wherever the variable occurs in the equation, and the statement you get out of all the numbers you have is not true, then you know the number is not a solution.
What is a number that can replace a variable in an equation to make it true called?
It's called the "solution" of the equation.
Is the solution to an equation any number that makes the equation true?
not always but most of the time yes
Why do we represent the solution to an inequality with a graph on a number line but we don't do the same for the solution to an equation?
An equation has an equal sign, which means that we know what the variable is equal to :)
What do you call the number that replaces a variable to make an equation?
The number that replaces a variable is the solution to the equation. great question, but it's only the answer.??
What does no solution in algebra mean?
An equation can have zero solutions, one solution, two solutions, or many solutions. A solution is any number that, when replaced into the equation, will give an equality. An example of an equation without a solution is x = x + 1. No matter what number you use for "x", the right part will always be one more than the left part. Therefore, the equation has no solution. (Also, if you subtract "x" from each side, you get the equation 0 = 1, which is obviously false.)
What is the number that can replace a variable in an equation to make it true?
The solution. If more than one, the solution set.
What is the discriminant and how is it used to solve equations using the quadratic formula?
It is not to solve so much as to see the number of solutions and whether there is a real solution to the equation. b2 - 4(a)(c) A positive answer = two real solutions. A negative answer = no real solution ( complex solution i ) If zero as the answer there is one real solution.
