Question

Solve Z = 9x + 9y for y.

Answer 1

Solving for y means that we want y to be on one side by itself so let's keep it on the left side

Z = 9x + 9y

Let's get rid of that 9x then. To do that we need to subtract 9x to both sides. What do we get then?

Answer 2

First, isolate y to one side. You can do this by subtracting 9x from both sides, and then further ridding 9y of 9 by dividing by 9.

Answer 3

Sorry I meant right side.

Answer 4

Z= 9y

Answer 5

wait didn't you subtract 9x on the left side?

Answer 6

-9x + z = 9y

Answer 7

great now we divide both sides by 9 . This will get rid of that 9 next to the y

Answer 8

-9x + z/9 =9y/9

Answer 9

y= -9x + z /9

Answer 10

yes\[\frac{-9x + z}{9} =y\]

Answer 11

good job

Answer 12

could it also be written as y = z - 9x/9?

Thanks for the help with problem
