#### Explanation:

#"simplify the right side"#

#8=4(-1)-7x=-4-7x#

#"add 4 to both sides"#

#12=-7x#

#"divide both sides by "-7#

#12/(-7)=xtox=-12/7#

#color(blue)"As a check"# Substitute this value into the right side of the equation and if equal to the left side then it is the solution.

#-4-(7xx-12/7)=-4-(-12)=-4+12=8#

#x=-12/7" is the solution"#
