Question

3. Check which of the following are solutions of the
equation x-2y = 4 and which are not:
(i) (0,2)
(ii) (2,0) (iii) (4,0) please solve this.... and don't post unnecessary ANS​

Answer 1

Then both sides are not equal then (0,2) is not the solution of equation

Then both sides are not equal then (0,2) is not the solution of equation x+2y=4

Then both sides are not equal then (0,2) is not the solution of equation x+2y=4(iii) Put the value x=4 and y=0 we get

Then both sides are not equal then (0,2) is not the solution of equation x+2y=4(iii) Put the value x=4 and y=0 we get4+2×0=4

Then both sides are not equal then (0,2) is not the solution of equation x+2y=4(iii) Put the value x=4 and y=0 we get4+2×0=4⇒4=4

Answer 2

Explanation:

given is x-2y=4

Put the value x=0 and y=2 we get

0-2×2=4

=0-4=4

=-4 =4

Then both sides are not equal then (0,2) is not the solution of equation
