# How do you solve 2x+3=9?

May 2, 2018

$x = 3$

#### Explanation:

$2 x + 3 = 9$

We want to find the variable $x$, so we have to make it alone. To do so, first subtract $\textcolor{b l u e}{3}$ from both sides of the equation:
$2 x + 3 \quad \textcolor{b l u e}{- \quad 3} = 9 \quad \textcolor{b l u e}{- \quad 3}$

$2 x = 6$

Now divide both sides by $\textcolor{b l u e}{2}$:
$\frac{2 x}{\textcolor{b l u e}{2}} = \frac{6}{\textcolor{b l u e}{2}}$

So the final answer is:
$x = 3$

Hope this helps!
