Kua tāruatia ki te papatopenga
-3w+21=-24
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-3w=-24-21
Tangohia te 21 mai i ngā taha e rua.
-3w=-45
Tangohia te 21 i te -24, ka -45.
w=\frac{-45}{-3}
Whakawehea ngā taha e rua ki te -3.
w=15
Whakawehea te -45 ki te -3, kia riro ko 15.
