HP dari SPLTV berikut adalah... X+2y+z=4 2x-y+3z=-3 3x+y-2z=7

[tex]x + 2y + z = 4 \\ x = 4 - 2y - z \\ x = 4 - 2y - z[/tex]
[tex]2x - y + 3z = -3 \\ 2x - 3 + y - 3x \\ x = - \frac{3}{2} + \frac{y}{2} - \frac{3}{2} z \\ x = \frac{ -3 +y}{2} - \frac{3}{2} z[/tex]
[tex]3x+y -2z = 7 \\ 3x = 7-y + 2z \\ x = \frac{7}{3} - \frac{y}{3} +\frac{2}{3}z \\ x = \frac{7 - y}{3} + \frac{2}{3} z[/tex]

semoga membantuuuu :)
