Kua tāruatia ki te papatopenga
y=64-1
Whakaarohia te whārite tuatahi. Tangohia te 1 mai i ngā taha e rua.
y=63
Tangohia te 1 i te 64, ka 63.
2x+63=87
Whakaarohia te whārite tuarua. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.
2x=87-63
Tangohia te 63 mai i ngā taha e rua.
2x=24
Tangohia te 63 i te 87, ka 24.
x=\frac{24}{2}
Whakawehea ngā taha e rua ki te 2.
x=12
Whakawehea te 24 ki te 2, kia riro ko 12.
y=63 x=12
Kua oti te pūnaha te whakatau.
