Question

Check which of the following are solutions of the equation x-2y=4 and which are not (0,2)

Answer 1

Answer:

f(x)= x-2y=4

given point= (0,2)

put x=0 and y=2

0-2(2)=4

-4=4

which is not true so

given point is not a solution of f(x)

Answer 2

$\huge\underline\bold{Answer:-}$

when x = 0 and y = 2

x - 2y = 4

0 - 2(2) = 4

0 - 4 = 4

-4 ≠ 4

LHS ≠ RHS

$\therefore$ (0,2) are not the solutions of the x-2y = 4
