Question

How do you solve `-2abs(y-7)+18=8`?

Answer 1

`y = 12` or `y = 2`

Explanation:

First subtract `18` from both sides
`-2abs(y-7) = 8-18`
`-2abs(y-7) = -10`

Then divide both sides by `-2`
`abs(y-7) = 5`

Since `abs(y-7) = 5`
`y-7 = 5` or `y-7 = -5`
`y = 5+7` or `y = -5+7`
`y = 12` or `y = 2`
