7.  3x  2  = 8 and  x + 1  = 1
What value of x satisfies both equations above?

If x+1 = 1,
x+1 is either 1 or 1, so
x = 0 or 2
Does either of those values satisfy the other equation?

Steve is it no solution?

Did you try the values?
x=0
3x2 = 3*02 = 2 = 2
x=2
3x2 = 3(2)2 = 62 = 8 = 8
This is the solution.
