$w = - 8$ $w = -8$

Rearrange the equation so you have $w$ $w$ 's on one side and normal numbers (constants) on the other.

$39 - 12 w = 7 - 16 w$ $39 - 12w = 7 - 16w$
$39 - 7 - 12 w = - 16 w$ $39 - 7 - 12w = -16w$
$39 - 7 = - 16 w + 12 w$ $39 - 7 = - 16w + 12w$

Simplify this to

$32 = - 4 w$ $32 = -4w$

and divide both sides by $4$ $4$ ,

$\frac{32}{4} = \frac{- 4 w}{4}$ $32/4 = (-4w)/4$

$8 = - w$ $8 = -w$

Therefore, if $8 = - w$ $8 = -w$ , then $- 8 = w$ $-8 = w$ .
