We can solve the question using the distributive property.

$7 (w + 20) - w = 5$ $7 (w + 20) -w = 5$

$(7 \cdot w) + (7 \cdot 20) - w = 5$ $(7 * w) + (7 *20) -w = 5$

$7 w + 140 - w = 5$ $7w + 140 -w =5$

$6 w + 140 = 5$ $6w +140 = 5$

Subtracting 140 from both sides

$6 w + 140 - 140 = 5 - 140$ $6w + 140-140 = 5-140$

$6 w = - 135$ $6w = -135$

$w = - \frac{135}{6} = - 22.5$ $w = -135 /6 = -22.5$

How do you solve for w in 7(w + 20) - w = 57(w+20)−w=57(w + 20) - w = 5?
