Question

For each equarion, write the equivalent equation that expresses y in terms of x
(Problem A)
3x+5x-y=5y

y=

(Problem B)
3x(5-x)= x-y

Answer 1

Get all the y terms on one side.

I will do B for you and let you do A.

First, get rid of the parenthesis.

15x-3x^2=x-y

Move the x and multiply by -1.

3x^2-14x=y

I hope this helps you to do the first problem. Thanks for asking.

Answer 2

8x^2=6y
