Whakaoti mō a, b, c
a=13
b=11
c=2
Tohaina
Kua tāruatia ki te papatopenga
b+c-b=2
Whakakapia te b+c mō te a i te whārite a-b=2.
b=-c+13 c=2
Me whakaoti te whārite tuarua mō b me te whārite tuatoru mō c.
b=-2+13
Whakakapia te 2 mō te c i te whārite b=-c+13.
b=11
Tātaitia te b i te b=-2+13.
a=11+2
Whakakapia te 11 mō te b me te 2 mō c i te whārite a=b+c.
a=13
Tātaitia te a i te a=11+2.
a=13 b=11 c=2
Kua oti te pūnaha te whakatau.
