Question

PLEASE HELP ME :(
Determine which system below will produce infinitely many solutions.

2x + 5y = 24
2x + 5y = 42
3x - 2y = 15
6x + 5y = 11
4x - 3y = 9
-8x + 6y = -18
5x - 3y = 16
-2x + 3y = -7

Answer 1

4x - 3y = 9 -->(2)
-8x + 6y = -18
----------------
8x - 6y = 18 (result of multiplying by 2)
-8x + 6y = -18
----------------add
0 + 0 = 0
0 = 0

when the answer comes out equal, example : 0 = 0, 2 = 2, 5 = 5, and so forth, the answer is INFINITE SOLUTIONS.
