Solve the pair:
2x - 9y = 10
4x - 9y = 20
Subtract the first from the second: 2x = 10 → x = 5.
Plug into 2x - 9y = 10: 10 - 9y = 10 → y = 0.
Solution: (x, y) = (5, 0).
2x - 9y = 10
4x - 9y = 20
Subtract the first from the second: 2x = 10 → x = 5.
Plug into 2x - 9y = 10: 10 - 9y = 10 → y = 0.
Solution: (x, y) = (5, 0).
