7w + 6 + 2w = (w + 2)
Sindrei [870]

Hey there!

The correct answer is w = \frac{-1}{2}

7w + 6 + 2w = w + 2          ~ Write the equation

9w + 6 = w + 2                   ~ Simplify

8w + 6 = 2                          ~ Subtract w from both sides

8w = -4                             ~ Subtract 6 from both sides

w = \frac{-1}{2}                                ~ Divide both sides by 8

Hope it helps and have a great day!
