# How do you solve 7=x-23?

Jun 19, 2018

$x = 30$

#### Explanation:

Solve:

$7 = x - 23$

Add $23$ to both sides of the equation.

$7 + 23 = x - 23 + 23$

Cancel $23$ on the right-hand side.

$7 + 23 = x - \textcolor{red}{\cancel{\textcolor{b l a c k}{23}}} + \textcolor{red}{\cancel{\textcolor{b l a c k}{23}}}$

Simplify.

$30 = x$

Switch sides.

$x = 30$
