Cara menyelesaikan kesamaan matrik dengan mencocokkan setiap elemen elemennya.
2 + p = 3p - 4
p - 3p = -4 - 2
- 2p = -6
p = 3
2p + q = - 1
2(3) + q = -1
q = -1 - 6
q = -7
9 + 2p = u
9 + 2(3) = u
u = 15
2p + 6r = 3q + 3
2(3) + 6r = 3(-7) + 3
6 + 6r = -21 + 3
6r = - 24
r = -4
s + 1 = 2r - 9
s + 1 = 2(-4)-9
s = -8-9-1 = -18
r + q = 6s + t
-4 -7 = 6(-18) + t
-11 = -108 + t
t = -11 + 108 = 97
Jadi, nilai p = 3, q = -7, r = -4, s = -18, t = 97 dan u = 15.
