# How do you solve X+3=2X-5?

Dec 27, 2015

$X = 8$

#### Explanation:

Given
$\textcolor{w h i t e}{\text{XXX}} X + 3 = 2 X - 5$

Subtract $X$ from both sides:
$\textcolor{w h i t e}{\text{XXX}} 3 = X - 5$

Add $5$ to both sides
$\textcolor{w h i t e}{\text{XXX}} 8 = X$

(Exchange the sides to get a more regular looking equation)
$\textcolor{w h i t e}{\text{XXX}} X = 8$
