Himpunan penyelesaian dari sistem persamaan 2x + 3y = 11 dan 3x- 2y =-1​

Jawaban:

2x + 3y = 11 |×3| 6x + 9y = 33

3x – 2y = -3 |×2| 6x – 4y = -6

13y = 39

y = 3

2x + 3y = 11

2x + 3(3) = 11

2x + 9 = 11

2x = 11 – 9

2x = 2

x = 1

Himpunan penyelesaian = {x, y} = {1, 3}

Sekian,semoga bermanfaat.
