# How do you solve 15x + 83 = -7?

Jul 14, 2018

$x = 6$

#### Explanation:

To solve for the variable $x$, we have to isolate it (make it by itself). To do so, first subtract $\textcolor{b l u e}{83}$ from both sides of the equation:
$15 x + 83 \quad \textcolor{b l u e}{- \quad 83} = - 7 \quad \textcolor{b l u e}{- \quad 83}$

$15 x = - 90$

Divide both sides by $\textcolor{b l u e}{15}$:
$\frac{15 x}{\textcolor{b l u e}{15}} = \frac{- 90}{\textcolor{b l u e}{15}}$

Therefore,
$x = 6$

Hope this helps!
