3 (3w − 4) = −20<br> Solve for w, please
Alborosie

Answer:

\boxed {x = -\frac{8}{9}}

Step-by-step explanation:

Solve for the value of w:

3(3w - 4) = -20

-Use <u>Distributive Property</u>:

3(3w - 4) = -20

9w - 12= -20

-Add both sides by 12:

9w - 12 + 12 = -20 + 12

9w = -8

-Divide both sides by 9:

\frac{9w}{9} = \frac{-8}{9}

\boxed {x = -\frac{8}{9}}

Therefore, the value of w is -\frac{8}{9}.
