#x = 27#

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

#-70 - 8x = 38 -4x#

#-8x = 108 - 4x#

#-4x = 108#

Divide both sides by -4 to find x.

#x = -27#

Check:

#-70 - (8 * -27) = 38 - (4 * -27)#

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

#-70 + 216 = 38 + 108#

# 146 = 146#
