# How do you solve -70- 8x = 38- 4x?

May 10, 2018

$x = 27$

#### Explanation:

First we should isolate our x. To this, add 70 to both sides, and add 4x to both sides as well.

$- 70 - 8 x = 38 - 4 x$

$- 8 x = 108 - 4 x$

$- 4 x = 108$

Divide both sides by -4 to find x.

$x = - 27$

Check:

$- 70 - \left(8 \cdot - 27\right) = 38 - \left(4 \cdot - 27\right)$

$- 70 - \left(- 216\right) = 38 - \left(- 108\right)$

$- 70 + 216 = 38 + 108$

$146 = 146$
