Answer 2

Step-by-step explanation:

Given equation is x-2y =4 .......>(1)

1) put x=4 and y=0 in (1)

LHS=4-2(0)

=4-0

=4

LHS=RHS

therefore (4,0) is a solution of x-2y=4.

2) put x=0 and y=2 in (1)

LHS= 0-2(2)

=0-4

=-4

LHS≠RHS

therefore,(0,2) is not a solution of x-2y=4.

solution : if the value of variable satisfies the given equation .i.e. LHS =RHS then the value of the variable is the solution or the root of the given equation.
