Use Gaussian elimination to solve the system: $+ 3y = 0$ and $3x + y = 3$ .

x = 1,\ y = 0

x = 0,\ y = 1

x = 2,\ y = -1

x = -1,\ y = 0

Use Gaussian elimination to solve the system: $3x + 3y = 15$ and $-3x + y = -7$ .

x = -3,\ y = -2

x = 3,\ y = 2

x = 2,\ y = 3

x = 4,\ y = 1

Use Gaussian elimination to solve the system: $3x - y = -14$ and $-2x - 2y = 4$ .

x = 2,\ y = -4

x = -4,\ y = 2

x = -3,\ y = 1

x = 4,\ y = -2
