solve for w. -9 + 8w = 9 + 10w w =

Explanation:

Step1: Move terms with w to one - side

Subtract 8w from both sides: $-9 + 8w-8w=9 + 10w-8w$ $-9=9 + 2w$

Step2: Isolate the term with w

Subtract 9 from both sides: $-9-9=9 + 2w-9$ $-18 = 2w$

Step3: Solve for w

Divide both sides by 2: $\frac{-18}{2}=\frac{2w}{2}$ $w=-9$

Answer:

$w = - 9$
