# How do you solve 5x-14=21?

Apr 29, 2018

$x = 7$

#### Explanation:

$5 x - 14 = 21$

We want to solve for the variable $x$, so we have to make it alone and move everything else to the other side of the equation.

First, add $\textcolor{red}{14}$ to both sides of the equation:
$5 x - 14 \quad \textcolor{red}{+ \quad 14} = 21 \quad \textcolor{red}{+ \quad 14}$

$5 x = 35$

Now divide both sides by $\textcolor{red}{5}$:
$\frac{5 x}{\textcolor{red}{5}} = \frac{35}{\textcolor{red}{5}}$

Therefore,
$x = 7$

Hope this helps!
