Question

If 7x-8y = 9 then y=
​

Answer 1

Step-by-step explanation:

To solve for y you need to get the y isolated.

The first step is to move the x over to the opposite side of the equation by using subtraction.

-8y=9-7x

Then to get the y alone you need to devide both sides by -8

-8y/-8=9-7x/-8

The final answer is going to be

y=-9+7x/8

Answer 2

Step-by-step explanation:

7x-8y=9

7x-9=8y

8y=7x-9

y=7x-9/8
