z=4
Tohaina
Kua tāruatia ki te papatopenga
z=\frac{12}{3}
Whakaarohia te whārite tuarua. Whakawehea ngā taha e rua ki te 3.
z=4
Whakawehea te 12 ki te 3, kia riro ko 4.
y-4=2
Whakaarohia te whārite tuatoru. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
y=2+4
Me tāpiri te 4 ki ngā taha e rua.
y=6
Tāpirihia te 2 ki te 4, ka 6.
x+6+4=15
Whakaarohia te whārite tuatahi. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
x+10=15
Tāpirihia te 6 ki te 4, ka 10.
x=15-10
Tangohia te 10 mai i ngā taha e rua.
x=5
Tangohia te 10 i te 15, ka 5.
x=5 y=6 z=4
Kua oti te pūnaha te whakatau.
