Question

Check whether (0,2) is a solution of the equation x-2y=4.​

Answer 1

let x= 0 and y = 2

substituting these in the equation,

x-2y= 4

0- 2(2)= 4

0- 4= 4

-4= 4

therefore (0,2) is not a solution of the equation

hope this helps!✌☺

Answer 2

$\huge \pink{hello \: there}$

Substituting the values of x and y in the given equation,

➡0-2(2)=4

➡0-4=4

➡-4≠4

As LHS≠RHS, (0,2) is not a solution of x-2y=4.
