  1. Number of solutions of the two equations 4x – y = 2 and 2y – 8x + 4 = 0 is
    1. zero
    2. one
    3. two
    4. infinitely many
Correct Option: D

4x – y = 2      ....(i)
2y – 8x + 4 = 0
⇒  8x – 2y = 4       .....(ii)
For simultaneous linear equations
a1x + b1y = c1
a2x + b2y = c2   if

a1
 +
b1
 +
c1
 ,   there are infinite solutions.
