Whakaoti mō z, a, b, c
c=50
Tohaina
Kua tāruatia ki te papatopenga
a=60-\frac{20}{2}
Whakaarohia te whārite tuarua. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
a=60-10
Whakawehea te 20 ki te 2, kia riro ko 10.
a=50
Tangohia te 10 i te 60, ka 50.
b=50
Whakaarohia te whārite tuatoru. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
c=50
Whakaarohia te whārite tuawhā. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
z=20 a=50 b=50 c=50
Kua oti te pūnaha te whakatau.
