# How do you solve 3x - 2= -20 ?

Jun 5, 2018

$3 x - 2 = - 20$

To solve for the variable $x$, we have to make it by itself. First, add $\textcolor{b l u e}{2}$ to both sides of the equation:
$3 x - 2 \quad \textcolor{b l u e}{+ \quad 2} = - 20 \quad \textcolor{b l u e}{+ \quad 2}$

$3 x = - 18$

Now divide both sides by $\textcolor{b l u e}{3}$:
$\frac{3 x}{\textcolor{b l u e}{3}} = - \frac{18}{\textcolor{b l u e}{3}}$

Therefore,
$x = - 6$

Hope this helps!
