Which of the following is not a solution of the linear equation x + 2y = 6?
(4, 2)
Substituting the given point in the equation x + 2y = 6,
(0, 3):
0 + (2 x 3) = 6
LHS = RHS
(4, 2):
4 + (2 x 2) ≠ 6
LHS≠ RHS
(2, 2):
2 + (2 x 2) = 6
LHS= RHS
(6, 0):
6 + (2 x 0) = 6
LHS = RHS
Hence, (4, 2) is not the solution of the given equation.
