Kua tāruatia ki te papatopenga
-2m-3=-6-6m+31
Pahekotia te m me -3m, ka -2m.
-2m-3=25-6m
Tāpirihia te -6 ki te 31, ka 25.
-2m-3+6m=25
Me tāpiri te 6m ki ngā taha e rua.
4m-3=25
Pahekotia te -2m me 6m, ka 4m.
4m=25+3
Me tāpiri te 3 ki ngā taha e rua.
4m=28
Tāpirihia te 25 ki te 3, ka 28.
m=\frac{28}{4}
Whakawehea ngā taha e rua ki te 4.
m=7
Whakawehea te 28 ki te 4, kia riro ko 7.
