Question

solve for m.
3 = -2(m + 8) - 11
m = \boxed{}

Explanation:

Step1: Add 11 to both sides

$3 + 11 = -2(m + 8) - 11 + 11$
$14 = -2(m + 8)$

Step2: Divide both sides by -2

$\frac{14}{-2} = \frac{-2(m + 8)}{-2}$
$-7 = m + 8$

Step3: Subtract 8 from both sides

$-7 - 8 = m + 8 - 8$
$-15 = m$

Answer:

$-15$
