-m+5=4m-10
Pahekotia te -2m me m, ka -m.
-m+5-4m=-10
Tangohia te 4m mai i ngā taha e rua.
-5m+5=-10
Pahekotia te -m me -4m, ka -5m.
-5m=-10-5
Tangohia te 5 mai i ngā taha e rua.
-5m=-15
Tangohia te 5 i te -10, ka -15.
m=\frac{-15}{-5}
Whakawehea ngā taha e rua ki te -5.
m=3
Whakawehea te -15 ki te -5, kia riro ko 3.
