Kua tāruatia ki te papatopenga
3x=2+4
Whakaarohia te whārite tuatahi. Me tāpiri te 4 ki ngā taha e rua.
3x=6
Tāpirihia te 2 ki te 4, ka 6.
x=\frac{6}{3}
Whakawehea ngā taha e rua ki te 3.
x=2
Whakawehea te 6 ki te 3, kia riro ko 2.
2-2y=3
Whakaarohia te whārite tuarua. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
-2y=3-2
Tangohia te 2 mai i ngā taha e rua.
-2y=1
Tangohia te 2 i te 3, ka 1.
y=-\frac{1}{2}
Whakawehea ngā taha e rua ki te -2.
x=2 y=-\frac{1}{2}
Kua oti te pūnaha te whakatau.
