7.  3x  2  = 8 and  x + 1  = 1
What value of x satisfies both equations above?
please show your work. I do notunderstand this.
Thank You

Steve,
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?

Deborah,
no they don't..I thought these were easy normally  feeling confused

Algebrahelp 
Deborah,
Steve is it no solution?

Algebrahelp 
Steve,
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.
