Let a,λ,μ∈R . Consider the system of linear equations
ax+2y3x−2y=λ=μ
Which of the following statement(s) is (are) correct?
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+μ=0 , then the system has no solution for a=−3
