Question

Check if (1, 1) is the solution of the equation x - 2y = 4.

Solution

(1, 1)

Putting x = 1 and y = 1 in the L.H.S of the given equation,

− 2y = 1 − 2(1) = 1 − 2 = − 1 ≠ 4

L.H.S ≠ R.H.S

Therefore, (1, 1) is not a solution of this equation.

  Is there an error in this question or solution?
