$x = 27$ $x = 27$

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

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

$- 8 x = 108 - 4 x$ $-8x = 108 - 4x$

$- 4 x = 108$ $-4x = 108$

Divide both sides by -4 to find x.

$x = - 27$ $x = -27$

Check:

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

$- 70 - (- 216) = 38 - (- 108)$ $-70 - (-216) = 38 - (-108)$

$- 70 + 216 = 38 + 108$ $-70 + 216 = 38 + 108$

$146 = 146$ $146 = 146$

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