Solve the system: y = x + 2, y = 3x - 2

Solve the system: 2y = 2x + 12, y = -2x - 3

Solve the system: 4x + 3y = -5, -2x + 2y = 6

Solve the system: 8x + 3y = 13, 3x + 2y = 11

Solve the system: -x + 2y = -6, 3x + 2y = 2

Solve the system: -5x + 4y = -16, x + 4y = 8

Solve the system: y = -2x + 2, y = 1/3x - 5

Solve the system: -2x + 3y = -9, x + y = 2

Solve the system: -3x - 4y = 2, 3x + 3y = -3
