Kua tāruatia ki te papatopenga
-4m+5=-15
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-4m=-15-5
Tangohia te 5 mai i ngā taha e rua.
-4m=-20
Tangohia te 5 i te -15, ka -20.
m=\frac{-20}{-4}
Whakawehea ngā taha e rua ki te -4.
m=5
Whakawehea te -20 ki te -4, kia riro ko 5.
