# How do you solve 3 - 5(x + 2) = 3(x + 1) + 6?

Jul 13, 2016

$x = - 2$

#### Explanation:

Use the distributive law to multiply out the brackets first so we have separate terms.

$3 - 5 \left(x + 2\right) = 3 \left(x + 1\right) + 6$

$3 - 5 x - 10 = 3 x + 3 + 6$

$\cancel{3} - 5 x - 10 = 3 x + \cancel{3} + 6$

$- 10 - 6 = 3 x + 5 x \text{ x terms on right to keep them positive}$
$- 16 = 8 x$

$x = - 2$
