If I recall the question that Steve already answered for you , it was
3x2 = 8 and  x+1 = 0
What he did was to solve the easier of the two, and then asked you to check if these answers satisfied the first.
Why did you not do that?
if x+1 = 1
then x+1 = 1 or x+1 = 1
x = 0 and x = 2
now test those in the first
if x = 0
LS =  3(0)  2
= 2 = 2
but RS = 8 , so x = 0 does NOT work in both
if x = 2
LS = (3(2)  2
= 8
= 8 = RS ,
so our solution is x = 2 , since it works in both equations.
