-6+4m=6m-4+12
Tangohia te 9 i te 3, ka -6.
-6+4m=6m+8
Tāpirihia te -4 ki te 12, ka 8.
-6+4m-6m=8
Tangohia te 6m mai i ngā taha e rua.
-6-2m=8
Pahekotia te 4m me -6m, ka -2m.
-2m=8+6
Me tāpiri te 6 ki ngā taha e rua.
-2m=14
Tāpirihia te 8 ki te 6, ka 14.
m=\frac{14}{-2}
Whakawehea ngā taha e rua ki te -2.
m=-7
Whakawehea te 14 ki te -2, kia riro ko -7.
