#1/3#

Explanation:

First, we add #10# to both sides.
#8x-10=-4x-6#
#8x-10color(blue)+color(blue)10=-4x-6color(blue)+color(blue)10#
Simplify.
#8x=-4x+4#
Add #4x# to both sides.
#8xcolor(blue)+color(blue)4color(blue)x=-4x+4color(blue)+color(blue)4color(blue)x#

Simplify.
#12x=4#
Then, divide both sides by 12.
#(12x)/12=4/12#
Simplify again.
#x=1/3#.
