Kua tāruatia ki te papatopenga
2m+8m-12=8
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te 2m-3.
10m-12=8
Pahekotia te 2m me 8m, ka 10m.
10m=8+12
Me tāpiri te 12 ki ngā taha e rua.
10m=20
Tāpirihia te 8 ki te 12, ka 20.
m=\frac{20}{10}
Whakawehea ngā taha e rua ki te 10.
m=2
Whakawehea te 20 ki te 10, kia riro ko 2.
