Answer:

#x=(-8)/13#

Explanation:

Given -

#-5=6x+3+7x#

Let us rewrite by taking the unknown to the left -

#6x+3+7x=-5#

Simplify

#13x+3=-5#

Add #-3 # to both sides

#13xcancel(+3) cancel(-3)=-5-3#

Simplify -

#13x=-8#

Multiply both sides with #1/13#

#cancel(13)x xx 1/(cancel13)=-8 xx 1/13#

#x=(-8)/13#
