Kua tāruatia ki te papatopenga
50-2z=12-14
Tāpirihia te 22 ki te 28, ka 50.
50-2z=-2
Tangohia te 14 i te 12, ka -2.
-2z=-2-50
Tangohia te 50 mai i ngā taha e rua.
-2z=-52
Tangohia te 50 i te -2, ka -52.
z=\frac{-52}{-2}
Whakawehea ngā taha e rua ki te -2.
z=26
Whakawehea te -52 ki te -2, kia riro ko 26.
