Harap bantuannya tentang matriks soal tertera pada gambar

PX = Q => X = P^-1 Q

(1 .. 2) A = (-1 ... 0)
(3 .. 4) ......(0 ... -1)

A = 1/(4 - 6) (4 ... -2) (-1 ... 0)
......................(-3 .... 1) (0 ... -1)

A = 1/(-2) (-4 + 0 .... 0 + 2)
................ (3 + 0 ..... 0 + -1)

A = (2 .......... -1)
...... (-3/2 ... 1/2)


Titik-titik = spasi
