Question

Tentukan himpunan penyelesaian
spldv dari persamaan 2x+3y-9=0 dan 3x+2y-1=o dengan metode eliminasi

Answer 1

2x + 3y - 9 =0 (x2) | 4x + 6y -18 = 0
3x + 2y - 1 =0 (x3) | 9x + 6y - 3 = 0
_______________-
5x - 15 = 0
5x = 15
x = 15/5
x = 3

2x + 3y - 9 = 0 (x3) | 6x + 9y - 27 = 0
3x + 2y - 1 = 0 (x2) | 6x + 4y - 2 = 0
________________-
5y - 25 = 0
5y = 25
y = 25/5
y = 5


semoga membantu
