Given
x + 4y = 6
and x=2y now substituting the value of x in first equation we get -
2y + 4y = 6
or 6y = 6
or y =1
Therefore x =2 (from equation 2)
So A>B

x + 4y = 6----1)
& x - 2y = 0----2)
---------------------
Adding equation 1) and 2)
we get, 6y = 6 which implies y = 1
substituting value of y in equation 2) , we get x = 2
hence x > y
So option A
& x - 2y = 0----2)
---------------------
Adding equation 1) and 2)
we get, 6y = 6 which implies y = 1
substituting value of y in equation 2) , we get x = 2
hence x > y
So option A
