Question

How do you solve for y in `-12x = 3(y - 3)`?

Answer 1

`y=-4x+3`

Explanation:

Expand `3(y-3)` first.
`-12x=3(y-3)`
`-12x=3y-9`

Now, you can work on isolating `y`.
`-12x=3y-9`
`-12x+9=3y`

Multiply both sides by 1/3 so we can cancel the coefficient of `y`.
`(1/3)(-12x+9)=(1/3)(3y)`
`-4x+3=y`

Final Answer
`y=-4x+3`.
