Actually the answer is
-3x + 5y = 15
2x + 3y = -10
You would have the square root symbol (called a radical) over the number 72. But if you mean to simplify it, you can keep in mind that 9 x 3 = 72 and the square root of 9 is 3, so then your answer would be
3(radical)3
Hope that's not too confusing!
