How do you solve -31-4x=-5-5(1+5x)?

Apr 19, 2017

$x = 1$

Explanation:

First of all, multiply the $- 5$ by $\left(1 + 5 x\right)$ to get

$- 5 - 25 x$

Separate the $x$'s and the numbers by exchanging them.

$- 31 - 4 x = - 5 - 5 - 25 x$

You get on one side:

$25 x - 4 x$

On the other:

$- 10 + 31$

$21 x = 21$
Divide by $21$ on both sides to get
$x = 1$
