Solution

(i) (3, 0)
Given equation: 2x - 3y = 6
Putting x = 3 , y = 0 in the given equation, we get:
LHS = 2×3 - 3×0 = 6 = RHS
So, it satisfies the given equation.

(ii) (0, 2)
Given equation: 2x - 3y = 6
Putting x = 0 , y = 2 in the given equation, we get:
LHS= 2×0 - 3×2 = -6RHS
So, it does not satisfy the given equation.

(iii) (2, 6)
Given equation: 2x - 3y = 6
Putting x = 2, y = 6 in the given equation, we get:
LHS = 2×2 - 3×6 = -14RHS
So, it does not satisfy the given equation.

(iv) (6, 2)
Given equation: 2x - 3y = 6
Putting x = 6, y = 2 in the given equation, we get:
LHS = 2×6 - 3×2 = 12 - 6 = 6 = RHS
So, it satisfies the given equation.

Hence, (3, 0), (6, 2) are the solutions of the given equation.
