# How do you solve x -2 = 9?

Jul 14, 2018

$x = 11$

#### Explanation:

To find the variable $x$, we have to isolate it (make it by itself).

To do so, add $\textcolor{b l u e}{2}$ to both sides of the equation:
$x - 2 \quad \textcolor{b l u e}{+ \quad 2} = 9 \quad \textcolor{b l u e}{+ \quad 2}$

Therefore,
$x = 11$

Hope this helps!
