I already asked this question once about the absolute value of 3x2=8 and absolute vale x+1=1....value of x?...and the answer I received was does 0 or 2 satisfy both ....they dont...so is it no solution?
Please help  I do not understand this problem....Thanks

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. 
Now I understand  I only asked for an explanation...I would have put those into place if I wasn't confused...thanks for the help..didn't mean to bother anyone!
