Answer 1

-28

Explanation:

Find 5y-3 , given -3y - 8 = 7.

First, we will multiply -3y - 8 = 7 by
`-(5)/(3)` to get 5y first.

`-(5)/(3) (-3y-8)=-(5)/(3) (7)\\5y+(40)/(3) =-(35)/(3) \\`

Now we will get the constant on the left side of the equation to 3.

`5y+(40)/(3) -(40)/(3) =-(35)/(3) -(40)/(3) \\5y=-25\\5y-3=-25-3\\5y-3=-28`
