Answer:

Question 8: x = -9

Question 9: x = 72

Step-by-step explanation:

Question 8:

9x = -81

Divide both sides by 9.

x = [tex]\frac{-81}{9}[/tex]

Divide −81 by 9 to get −9.

x = -9

Question 9:

-12 = -[tex]\frac{x}{6}[/tex]

Multiply both sides of the equation by 6.

-72 = -x

Swap sides so that all variable terms are on the left-hand side.

-x = -72

Multiply both sides by −1.

x = 72
