4x + 8 = -4 ----- (-8 on both sides) 4x = -12 ----- (divide by 4 on both sides) x = -3
check the work: 4x+8=-4 ---- 4 x -3 + 8 = -4 ----- (mult.) -12 + 8 = -4 ----- (add) -4 = -4 or 1 = 1
answer is x = -3

4x+8= -4; 4x= -12; so x= -3

Too easy.
x= -3
x= -3
2008-03-18 1:47 pm
4x + 8 = -4
4x = -4 - 8
4x = -12
x = -12/4
x = -3
4x = -4 - 8
4x = -12
x = -12/4
x = -3

4x+8=-4?
-8 from both sides to get 4x by itself.
4x+8=-4
....-8...-4
4x=-12

4......4
x=-3
CHECK BY SUBSTITUTION:
4(-3)+8=-4
-12+8=-4
-4=-4
LHS=RHS
