Nobody can help you find a solution until you get another equation to go along with this one.
Your equation has two variables in it ... 'x' and 'y' ... so it has no unique solution all by itself.
what is the solution of x-5y=10 and 2x-10y=20
Get two slaves. Give one equation to each slave. Say, "Go!"
Give us the whole equation, and we can help.
The number 3 equals x when it has the same value in an equation. This is used to help solve a specific problem in math where certain variables are unknown.
In a math equation, something equals something else. You haven't given any equation to work with. I'm thinking you're looking to find 'x' when 'y' equals 2, when 'y' equals 3, etc. But we need some more info to help you.
You can take the logarithm on both sides of an equation. The real trick is to figure out when this will help you to solve the equation, and when not.
7y = 3y - 12 4y = -12 y = -3
I will help.... You have to solve for x 1) simplify 2x-6=4 2) 2x=? 2) x=? Hint make 6 equal zero on the left side of the equation
It combines like terms and results in the least amount if variables to solve for
If you mean 3x2+4x-2 = 0 then it can be solved by means of the quadratic equation formulla
It tells you the order in which the equation needs to be simplified.
A proper question would help.
If you don't know something in a math equation you can replace it with a variable and then solve it algebraically.
Solve it as you would normally. I could help if I had the equation. :) Fractions don't really change much; they just make the problem look more difficult.
Type your answer here...
Graphs help you solve equations, and equations help you solve graphs. Because the graph is a diagram of the equation, showing at its simplest the y answer for each value of x.
3 - x = 12x - 1 Add x to both sides of the equation: 3 = 13x - 1 Add 1 to both sides of the equation: 4 = 13x Divide both sides of the equation by 13: 4/13 = X
Can you help with this equation? Thanks. Solve for x and y and z for the following. x plus y plus z equals 9 x plus 2y plus 3z equals 23 x plus 5y plus -3z equals -7
first we should understand the question,then we should know the formula.
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.
A situation equation follows the order of the story problem.For instance:Johnny has 8 apples, he eats some, and has 3 left.The situation equation would be: 8 - a = 3A solution equation is the equation that would help you find the solution. Your brain doesn't automatically know what "a" is, it has to rearrange the order of the equation and then solve.The solution equation would be: 8 - 3 = a, then you would solve it.
-3x = 3 + y 3 + y - 5y = -21 -4y = -24 y = 6 x = -3
The two negatives make a positive. So, make a "U" with the two negative signs, and it will always remind you to add them together! So, 46 - - 12 = 58
An equation has the 'equals' sign ( = ) in it. An expression hasn't.
Mathematical signs would help.
