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