diketahui matriks A = (5 3) .                                    (3 2) dan B = (4 -2) .             (-6 3) Matriks X yang memenuhi XA + B = X adalah

Matrix
(a b) (5 3) + (4 -2) = (a b)
(c d) (3 2) (-6 3) (c d)

(5a+3b+4 3a+2b-2) = (a b)
(5c+3d-6 3c+2d+3) (c d)

4a+3b=-4 ; 3a+b=2 -> a = 2, b = -4
4c+3d=6 ; 3c+d=-3 -> c = -3, d = 6

Hence,
X = (2 -4) -> Jawab
(-3 6)
