The above system of equations can be written as

or AX = B

Where A = B = and X =

|A| = – 12 + 12 = 0

So, A is singular,Now X will be consistence if (Adj A)xB = 0

C₁₁ = (– 1)^{1 + 1} – 3 = – 3

C₁₂ = (– 1)^{1 + 2} 6 = – 6

C₂₁ = (– 1)^{2 + 1} – 2 = 2

C₂₂ = (– 1)^{2 + 2} 4 = 4

Also, adj A =

=

(Adj A).B =

=

Hence, The given system is inconsistent.
