Tentukanlah nilai-nilai p, q, r, dan s
pada persamaan matriks berikut!
[tex]5 \left[\begin{array}{ccc}r&s\\p&q\end{array}\right] - \left[\begin{array}{ccc}8&-3\\5&6\end{array}\right] = \left[\begin{array}{ccc}7&8\\-15&14\end{array}\right][/tex]
pada persamaan matriks berikut!
[tex]5 \left[\begin{array}{ccc}r&s\\p&q\end{array}\right] - \left[\begin{array}{ccc}8&-3\\5&6\end{array}\right] = \left[\begin{array}{ccc}7&8\\-15&14\end{array}\right][/tex]

1. Jawaban ekamiaww
5r - 8 = 7
5r = 7 + 8
5r = 15
r = 3
5s - (-3) = 8
5s + 3 = 8
5s = 8 - 3
5s = 5
s = 1
5p - 5 = -15
5p = -15 + 5
5p = -10
p = -2
5q - 6 = 14
5q = 14 + 6
5q = 20
q = 4
semoga membantu ya.. :) -
