Answer:
10 isn't the right answer
Step-by-step explanation:
multiply everything in the parenthesis by -4
you would get 3x-8-12x=82
then combine like terms to get -9x
once your equation is in simplist form it will look like
-9x-8=82
next you add 8 to the 82
-9x=90
then divide 90 by -9 and you would get
x=-10
