# How do you solve "-8-x=x-4x"?

Feb 23, 2018

#### Explanation:

$- 8 - x = x - 4 x$

You can subtract $4 x$ from $x$ and get:

$- 8 - x = - 3 x$

Then you add the $x$ to both sides, which cancels out the $x$ on the left side and get:

$- 8 = - 2 x$

Then divide both sides by $- 2$ and get:

$4 = x$

Hope that helps.

$x = 4$

#### Explanation:

$- 8 - x = x - 4 x$

$- 8 - x = - 3 x$

Add $3 x$ to both sides#

$- 8 - x + 3 x = - 3 x + 3 x$

$- 8 - x + 3 x = 0$

$- 8 + 2 x = 0$

Then add $- 8$ to both sides

$- 8 + 2 x + 8 = 0 + 8$

$2 x = 8$

Finally, divide both sides by $2$

$\frac{2 x}{2} = \frac{8}{2}$

$x = 4$
