# How do you solve 15x - 7= 3+ 13x?

Jun 21, 2017

x = 5

#### Explanation:

We need to get the variable on one side only and isolate the x.

1. Subtract $13 x$ from both sides of the equation.

$15 x - 7 - \textcolor{b l u e}{13 x} = 3 \cancel{+ 13 x} \cancel{\textcolor{b l u e}{- 13 x}}$

$2 x - 7 = 3$

2. Add 7 to both sides.

$2 x \cancel{- 7} \cancel{+ \textcolor{b l u e}{7}} = 3 \textcolor{b l u e}{+ 7}$

$2 x = 10$

3. Divide both sides by 2.

$\frac{2 x}{2} = \frac{10}{2}$

$x = 5$
