# How do you solve 47=w-(-8)?

Sep 19, 2016

Add $\left(- 8\right)$ (or subtract $\left(+ 8\right)$ from both sides to get
$\textcolor{w h i t e}{\text{XXX}} w = 39$

#### Explanation:

$47 = w - \left(- 8\right)$

$\rightarrow 47 \textcolor{b l u e}{+ \left(- 8\right)} = w \cancel{- \left(- 8\right)} \cancel{\textcolor{b l u e}{+ \left(- 8\right)}}$

$\rightarrow 39 = w \textcolor{w h i t e}{\text{XXX")orcolor(white)("XXX}} w = 39$
