diketahui matriks A =( 2p , 2r,P, -3) Dan B=(3q,3s,-2,2s) dan C =(5p-q,6r,3p,2q-4s) serta 2A-b=C. nilai pqrs =

2A-B = didapat
1) 2p+2=3p
2p-3p = 2
-p = 2
P= -2
2) r+2 = 3p
r +2 = 3(-2)
r+2 = -6
r = -8
3) 4p-3q = 5p-q
4(-2)-3q = 5(-2)-q
-8-3q = -10-q
-3q + q = -10+8
-2q = -2
q = 1
4) -6-2s = 2q-4s
-6-2s = 2(1)-4s
-6-2s = 2-4s
-2s+4s = 2+6
2s = 8
S = 4
