Solve x + y - z = 0, x - y + 3z = 8, x - y - z = -4 (x, y, z) = (1, 2, 3)
Solve y = x + 3, 2x + y = 9 (x, y) = (2, 5)
Solve x - y - z = -3, x - y + z = 3, x + 3y + z = 15 (x, y, z) = (3, 3, 3)
Solve x = 3y - 2 and 2x + y = 10 (x, y) = (4, 2)
Solve x + 3y + z = 12, x - y - z = 0, x - y + z = 8 (x, y, z) = (5, 1, 4)
