EXPLANATION.
⇒ 2x + y = 5. - - - - - (1).
⇒ 4x + 2y = 10. - - - - - (2).
As we know that,
We can write equation (1) as,
⇒ 2x + y = 5. - - - - - (1).
⇒ y = 5 - 2x. - - - - - (1).
Put the value of y = 5 - 2x in equation (2), we get.
⇒ 4x + 2(5 - 2x) = 10.
⇒ 4x + 10 - 4x = 10.
⇒ x = 0.
Put the value of x = 0 in equation (1), we get.
⇒ y = 5 - 2x.
⇒ y = 5 - 2(0).
⇒ y = 5.
Values of x = 0 and y = 5
