# How do you solve 3= \frac { x + 25} { 6}?

Jan 25, 2018

$x = - 7$

#### Explanation:

$3 = \frac{x + 25}{6}$

Multiply by $6$ on both sides.

$3 \cdot 6 = \frac{\cancel{6} \left(x + 25\right)}{\cancel{6}}$

$x + 25 = 18$

Subtract $25$ from both sides.

$x = 18 - 25$

$x = - 7$

$x = - 7$

#### Explanation:

$3 = \frac{x + 25}{6}$

Let's start by doing *cross multiply

$x + 25 = 3 \ast 6$

$x + 25 = 18$

Subtract $25$ from both sides

$x \cancel{+ 25} \cancel{\textcolor{red}{- 25}} = 18 - \textcolor{red}{25}$

$x = - 7$
