# How do you solve y - 28= -28?

Nov 27, 2015

$y = 0$

#### Explanation:

$- 28$ is equivalent to $0 - 28$

Therefore
$\textcolor{w h i t e}{\text{XXX}} \textcolor{red}{y} - 28 = - 28$
is equivalent to
$\textcolor{w h i t e}{\text{XXX}} \textcolor{red}{y} - 20 = \textcolor{red}{0} - 28$

and thus
$\textcolor{w h i t e}{\text{XXX}} \textcolor{red}{y} = \textcolor{red}{0}$
