Kua tāruatia ki te papatopenga
2x=5+1
Whakaarohia te whārite tuatahi. Me tāpiri te 1 ki ngā taha e rua.
2x=6
Tāpirihia te 5 ki te 1, ka 6.
x=\frac{6}{2}
Whakawehea ngā taha e rua ki te 2.
x=3
Whakawehea te 6 ki te 2, kia riro ko 3.
4y+2\times 3=7
Whakaarohia te whārite tuarua. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
4y+6=7
Whakareatia te 2 ki te 3, ka 6.
4y=7-6
Tangohia te 6 mai i ngā taha e rua.
4y=1
Tangohia te 6 i te 7, ka 1.
y=\frac{1}{4}
Whakawehea ngā taha e rua ki te 4.
x=3 y=\frac{1}{4}
Kua oti te pūnaha te whakatau.
