Hi ,
x = 2y
x - 2y = 0 ---- ( 1 )
y = 2x
-2x + y = 0----- ( 2 )
compare equations ( 1 ) and ( 2 ) with
a1x + b2 y + c1 = 0 and a2x + b2 y + c2 = 0
a1 = 1 , b1 = -2 , c1 = 0
a2 = -2 , b2 = 1 , c2 = 0
Now find ,
a1 /a2 = 1 / ( -2 ) = - 1/2
b1 / b2 = -2 /1 = -2
∴ a1 / a2 ≠ b1 / b2
The given equations shows two intersecting lines .
put x= 0 in equation ( 1 ) we get y = 0
intersecting point is ( 0 , 0 )
I hope this helps you .

We know that linear equations having unique solution must have the form,a1/a2not equal to b1/b2
