# How do you solve 4x + 7= 13?

Apr 30, 2018

$x = \frac{3}{2}$ or $1.5$

#### Explanation:

$4 x + 7 = 13$

To solve this, we need to get the variable $x$ by itself. To do so, let's move everything else to the other side of the equation:

First, subtract both sides by $\textcolor{red}{7}$:
$4 x + 7 \quad \textcolor{red}{- \quad 7} = 13 \quad \textcolor{red}{- \quad 7}$

$4 x = 6$

Now divide both sides by $\textcolor{red}{4}$:
$\frac{4 x}{\textcolor{red}{4}} = \frac{6}{\textcolor{red}{4}}$

$x = \frac{6}{4}$

Divide numerator and denominator by $\textcolor{red}{2}$:
$x = \frac{6}{4} \textcolor{red}{\div \frac{2}{2}}$

$x = \frac{3}{2}$ or $1.5$

Hope this helps!
