Question

Which of the following is not a solution of the linear equation x + 2y = 6?

• A. (0, 3)
• B. (4, 2)
• C. (2, 2)
• D. (6, 0)

Answer 1

The correct option is B

(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) $\ne$ 6
LHS$\ne$ 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.
