matt thinks that all the values of x and y that absolute value   would make this statment true
x+y= x+y
if x is 5 and y is 6 then replacing x and y for the values would look like this:
x+y=5+6= 11=11
x+y= 5+6=5+6=11
Is matt a true smarty pants? could matt be proven wrong? show work to try and prove him wrong. also explain in words how you got the answer
