# How do you solve 3x - 7 = 23?

Apr 29, 2018

$x = 10$

#### Explanation:

$3 x - 7 = 23$

To solve for $x$ we have to make $x$ alone, so let's move everything else to the other side of the equation.

First, add $\textcolor{red}{7}$ to both sides of the equation:
$3 x - 7 \quad \textcolor{red}{+ \quad 7} = 23 \quad \textcolor{red}{+ \quad 7}$

$3 x = 30$

Now divide both sides by $3$:
$\frac{3 x}{\textcolor{red}{3}} = \frac{30}{\textcolor{red}{3}}$

$x = 10$

Hope this helps!
