x+7-x+1=8
x – x cancel out,
7+1=8
8=8 correct.
“if it were x+7+x+1 would it then be 8x^2?”
no, it would not. it would only be squared if the x’s were being multiplied. like,
x*x*8 = 8x^2
x*x+8 = x^2 + 8

yes think of it like this you have a x and you have a -x they can cancel out then you have a 7+1 which is 8. so you are left with 8=8. so this statement is ture for all real numbers.
