himpunan penyelesaian sistem persamaan 4x-3y=15 dan -3x-2y=-12 adalah

4x - 3y = 15    ║×2║  8x - 6y = 30
-3x - 2y = -12  ║×3║ -9x - 6y = -36
                                  __________ -
                                        17x = 66
                                            x = 3,882
4x - 3y = 15
15,529 - 3y = 15
-3y = 15 - 15,529
-3y = -0,529
y = 0,176
