$w = 6$ $w=6$

Explanation:

$\frac{1}{2} w + 7 = 2 w - 2$ $1/2w+7=2w-2$
First, subtract $2 w$ $2w$ from each side.
$- \frac{3}{2} w + 7 = - 2$ $-3/2w+7=-2$
Next, subtract 7 from each side.
$- \frac{3}{2} w = - 9$ $-3/2w=-9$
Finally, multiply each side by the reciprocal of the coefficient of $w$ $w$ , which is $- \frac{3}{2}$ $-3/2$ . (Multiply each side by $- \frac{2}{3}$ $-2/3$ )
$w = 6$ $w=6$
