Kua tāruatia ki te papatopenga
5m-32-2m=28
Tangohia te 2m mai i ngā taha e rua.
3m-32=28
Pahekotia te 5m me -2m, ka 3m.
3m=28+32
Me tāpiri te 32 ki ngā taha e rua.
3m=60
Tāpirihia te 28 ki te 32, ka 60.
m=\frac{60}{3}
Whakawehea ngā taha e rua ki te 3.
m=20
Whakawehea te 60 ki te 3, kia riro ko 20.
