dengan metode matriks tentukan himpunan penyelesaian soal berikut . a. 5x + 3y = 11 dibawah 6x +.4y = 12

(5 3) (x) = 11
(6 4) (y) = 12

(x) = (5 3)(pangkat -1) (11)
(y) = (6 4) (12)
(x) = 1. (4 -3) (11)
-
(y) = 20-18 (-6 5) (12)
(x)= 1 (4x11+(-3)x12)
-
(y)= 2 ((-6)x11+5x12)

x
y = 1 (8)
- (-6)
2
jadi x = 4 y=-3
