Question

is(0,2) solution of linear equations x-2y =4?justify

Answer 1

x-2y=4
To check whether the given point(0,2) is the solution of this equation. Just put the points of the solution in equation.
L.H.S.
x-2y = 0-2(2) = -4 ≠ R.H.S.
Hence (0,2) is not the solution of given linear equation.

Answer 2

L.H.S x = 0 , y = 2
x-2y
0-2 X 2
0-4 =
-4
R.H.S = 4
L.H.S. not equal to R.H.S.
(0,2) is not a solution of the equation x-2y=4
