(i) 2x + y = 6
x - 2y = - 2
Unique solution at x = 2, y = 2
Lines meet x - axis at (3, 0) and (- 2, 0)
(ii) 2x - y = 2
4x - y = 8
Unique solution at x = 3, y = 3
Lines meet x - axis at (1, 0) and (2, 0)
(iii) x + 2y = 5
2x - 3y = - 4
Unique solution at x =1, y = 2
Lines meet x - axis at (5, 0) and (- 2, 0)
(iv) 2x + 3y = 8
x - 2y = - 3
Unique solution at x =1, y = 2
Lines meet x - axis at (4, 0) and (- 3, 0)
