How do you define a variable in terms of another

Question

Please make it fast. 

Answer 1

Solving for 1 variable in terms of one or more other variables means solving a multiple variable equation for the equivalent expression.

 

For example.

 

    In the equation 

 

       x + 2y = 10

 

If i solved for x in terms of y, I would isolate x on one side of the equals sign.

 

       by adding -2y to both sides,  we end up with

 

       x = -2y + 10

 

 Thus x in terms of y is -2y + 10

 

This phrase is used a lot on standardized tests ... SAT, ACT, etc.
