# How do you evaluate x-(-y) where x=-2 and y=5?

Jan 11, 2017

Substitute $\textcolor{red}{- 2}$ for $x$ and Substitute $\textcolor{b l u e}{5}$ for $y$ and calculate. See process below:

#### Explanation:

$\textcolor{red}{x} - \left(- \textcolor{b l u e}{y}\right)$ becomes:

$\textcolor{red}{- 2} - \left(- \textcolor{b l u e}{5}\right)$

Because in addition and subtract minus a negative number becomes a plus, we can rewrite as:

$\textcolor{red}{- 2} + \textcolor{b l u e}{5}$

$3$
