MathematicsDeterminantsJEE Main
Options:
  • A If a=-3, then the system has infinitely many solutions for all values of λ and μ
  • B If a-3, then the system has a unique solution for all values of λ and μ
  • C If λ+μ=0, then the system has infinitely many solutions for a=-3
  • D If λ+μ0, then the system has no solution for a=-3

The correct answer is: If a=-3, then the system has infinitely many solutions for all values of λ and μ
ax+2y=λ
3x-2y=μ
For a=-3, above lines will be parallel or coincident
Also parallel for λ+μ0 and coincident λ+μ=0
and if a-3, lines are intersecting unique solution.
