Question

Check whether (√2,4root2
is a solution of the equation x – 2y = 4 or not ?

Answer 1

root 2 ,four root 2)-[1]

x-2y=4.-[2]

therefore,substituting [1] in [2].

root 2 +2(4 root 2)

=root 2 +8 root 2.

=9 root 2

=9(1.414)

=12.7.

this is not equal to 4. therefore (root2, 4 root2) is not the solution of the equation x-2y=4
