Whakaoti mō x, y, z
x=4
y=-2
z=3
Tohaina
Kua tāruatia ki te papatopenga
x=-y-z+5
Me whakaoti te x+y+z=5 mō x.
-y-z+5-y+z=9 2\left(-y-z+5\right)+2y+3z=13
Whakakapia te -y-z+5 mō te x i te whārite tuarua me te tuatoru.
y=-2 z=3
Me whakaoti ēnei whārite mō y me z takitahi.
x=-\left(-2\right)-3+5
Whakakapia te -2 mō te y me te 3 mō z i te whārite x=-y-z+5.
x=4
Tātaitia te x i te x=-\left(-2\right)-3+5.
x=4 y=-2 z=3
Kua oti te pūnaha te whakatau.
