Q. 5 B

# Solve the following system of equations by elimination method:x + y = 2xyx – y = 6xy

Given pair of linear equations is

x + y = 2xy …(i)

And x – y = 6xy …(ii)

On adding Eq. (i) and Eq. (ii), we get

x + y + x – y = 2xy + 6xy

2x = 8xy

On putting in Eq. (ii), we get

4x – 1 = 6x – 1 = 6x – 4x

– 1 = 2x

On putting x = 0 , we get y = 0

Hence, and , which is the required solution.
