Answer» Given equation :3x + 2y = 10 (i) (2,2) Substitute (2,2) in 3x + 2y = 10 x = 2 ; y = 2LHS RHS3 (2) + 2(2) = 10 = 6 + 4= 10 10 = 10 LHS = RHS ∴ (2,2) is a SOLUTION to the equation 3x + 2y = 10 (ii) (1,5)Substitute (1,5) in 3x + 2y = 10 x = 1 ; y = 5LHS RHS3 (1) + 2 (5) = 10= 3 + 10 = 13 13 ≠ 10LHS ≠ RHS∴ (1,5) is not a solution to the equation 3x + 2y = 10 |
