Answer:

9y - 9 = - 27

Step-by-step explanation:

Given

-4y - 1 = 7 ( add 1 to both sides )

4y = 8 ( divide both sides by -4 )

y = -2

Then

9y - 9 = 9(-2) - 9 =- 18 - 9 = - 27

-4y - 1 = 7
add 1 to both sides
-4y = 8
divide both sides by -4
y = -2

plug in y = -2 into 9y - 9
9(-2) - 9
-18 - 9 = -27

answer: -27
