Multiply the first equation by 6 and the second by 4 to clear denominators: 2x - 3y = -24 and 2x + y = -8.
Subtract the second new equation from the first: (2x - 3y) - (2x + y) = -24 - (-8), which simplifies to -4y = -16, so y = 4.
Substitute y = 4 into the second new equation: 2x + 4 = -8, so 2x = -12, which means x = -6.
Solution: x = -6, y = 4.
