In simplistic terms, X is the number on the left in (), and Y is the number on the right.
So using 8:
8(squared) = 72 - 8
64 = 64
Or
8(squared) + 8 = 72
64 + 8 = 72
Or
8 = 8(squared) + 8
8 = 64 + 8
8 = 72

56 ???????
They skipped 7 and 8
damn bruh I didn't even read the left side of the problem. I just read the right. then it should be 90 if you factor the pattern on the left.
