Himpunan penyelesaian dari sistem persamaan 3 x kurang 2 y = 1 dan 2 x + 3y = 18 adalah​

3x – 2y = 1 | x 3 |

9x – 6y = 3

2x + 3y = 18 | x 2 |

4x + 6y = 36

9x – 6y = 3

4x + 6y = 36

___________ +

13x = 39

x = 39/13

x = 3

Subtitusikan x = 3 ke persamaan 1

3x – 2y = 1

3(3) – 2y = 1

9 – 2y = 1

-2y = 1 – 9

-2y = -8

y = -8/-2

y = 4

Jadi HP = {(3,4)} (d.)

Semoga membantu
