From the first equation: y=(λ2)xy = (\lambda-2)x . Substitute this value into the second equation we get

4x(λ2)x=λ(λ2)x4x -(\lambda-2)x = \lambda(\lambda-2)x , as x0x \ne 0 6λ=λ22λ6-\lambda = \lambda^2-2\lambda , or

λ2λ6=0\lambda^2-\lambda - 6 =0 . This equation has two solutions: λ=2\lambda =-2 and λ=3\lambda =3
