Carilah sistem pemecahan dari sistem persamaan berikut (bebas memilih metode)

2x + y + 4z = 16 | x 2 |

4x + 2y + 8z = 32

3x + 2y + z = 10

____________ –

x + 7z = 22 | x 5 |

5x + 35z = 110

2x + y + 4z = 16 | x 3 |

6x + 3y + 12z= 48

x + 3y + 3z = 16

_____________ –

5x + 35z = 110

5x + 9z = 32

___________ –

26z = 78

z = 78 / 26

z = 3

5x + 9z = 32

5x + 9(3) = 32

5x + 27 = 32

5x = 32 – 27

5x = 5

x = 1

2x + y + 4z = 16

2(1) + y + 4(3)= 16

2 + y + 12 = 16

y = 16 – 12 – 2

y = 2

jadi x = 1 , y = 2 , z = 3
