Tentukan himpunan tersebut menggunakan sistem metriks x+2y+z = 4 2x+2y+z = 5 3x+y+3z = 7

Sory, tulisannya acak2an, males nulis... Jawabannya gatau bner gatau salah hehehe

Kelas : X SMA

x + 2y + z = 4 ............... (1)
2x + 2y + z = 5 ........... (2)
3x +y + 3z = 7 .............. (3)

x + 2y + z = 4
2x+ 2y + z = 5

-x = -1
x = 1

x + 2y + z = 4 ..........×3
3x + y + 3z = 7 ........ ×1

3x + 6y + 3z = 12
3x + y + 3z = 7

5y = 5
y = 1

x + 2y + z = 4
1 + 2(1) + z = 4
1 + 2 + z = 4
3 + z = 4
z = 4 - 3
z = 1
