Whakaoti mō x, y, z
x=2
y=3
z=3
Tohaina
Kua tāruatia ki te papatopenga
x=-y-z+8
Me whakaoti te x+y+z=8 mō x.
2\left(-y-z+8\right)+3y+2z=19 4\left(-y-z+8\right)+2y+3z=23
Whakakapia te -y-z+8 mō te x i te whārite tuarua me te tuatoru.
y=3 z=-2y+9
Me whakaoti ēnei whārite mō y me z takitahi.
z=-2\times 3+9
Whakakapia te 3 mō te y i te whārite z=-2y+9.
z=3
Tātaitia te z i te z=-2\times 3+9.
x=-3-3+8
Whakakapia te 3 mō te y me te 3 mō z i te whārite x=-y-z+8.
x=2
Tātaitia te x i te x=-3-3+8.
x=2 y=3 z=3
Kua oti te pūnaha te whakatau.
