If you would like to find the solution to the system of equations, you can do this using the following steps:

2x = 5y + 4 ... 2x - 5y = 4     /*(-3)
3x - 2y = -16                       /*2
_____________
-6x + 15y = -12
6x - 4y = -32
_____________
-6x + 15y + 6x - 4y = -12 - 32
11y = -44    /11
y = - 44/11
y = -4

2x = 5y + 4
2x = 5 * (-4) + 4 = -20 + 4 = -16
2x = -16
x = -16/2
x = -8

(x, y) = (-8, -4)

The correct result would be (-8, -4).
