The given system of equations is:

1) 3x - 2y = 11
2) 4x - 3y = 3
3) 12x - 8y + 12x - 15y = 35
4) 3x - 2y = 11
5) 7y = 35
6) 3x - 2y = 11
7) 12x - 8y = 44
8) 12x - 15y = 9

From equation 5, we can solve for y:
7y = 35
y = 5

Substituting y = 5 into equation 1, we can solve for x:
3x - 2(5) = 11
3x - 10 = 11
3x = 21
x = 7

Therefore, the solution to the system of equations is (x, y) = (7, 5).
