I doesn't seem right to me. You can use an online calculator where all you do is input the values. Search for "parabolic motion calculator" or something along those lines. Hope it helps.
5x + 2y = 7....multiply by -1
-2x + 2y = -14
----------------
-5x - 2y = -7 (result of multiplying by -1)
-2x + 2y = -14
---------------add
-7x = - 21
x = -21/-7
x = 3
5x + 2y = 7
5(3) + 2y = 7
15 + 2y = 7
2y = 7 - 15
2y = - 8
y = -8/2
y = -4
solution is (3,-4)
