Use the method of elimination to solve each other of the pair of simultaneous equations: 11y + 15x = -23 and 7y - 2x = 20
x = 1, y = 0
x = -3, y = 2
x = -3, y = -2
x = 0, y = -1
2
Use the method of elimination to solve each other of the pair of simultaneous equations: 5x - 6y = 2 and 6x - 5y = 9
x = 6, y = 1
x = 4, y = 3
x = -4, y = 3
x = 4, y = -3
3
Use the method of elimination to solve each other of the pair of simultaneous equations: x + y = 0 and x - y = 2
x = 1, y = -1
x = -1, y = -1
