The system of linear equations,
4x+2y=7
2x+y=6
has,
(A) a unique solution
(B) no solution
(C) an infinite number of solutions (D) exactly two distinct solutions

• (B) no solution
  because in a system of equations
  a1x+b1y=c1...(i)
  a2x+b2y=c2...(ii)
  if a1/a2=b1/b2..(iii)
  then this system of equations will have no solution.
  and in the given question
  4/2=2/1
  => 2/1=2/1
  that satisfy equation (iii)
  so there will not be any solution of the given question.
