Kua tāruatia ki te papatopenga
3=18+5x
Whakareatia ngā taha e rua o te whārite ki te 3.
18+5x=3
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
5x=3-18
Tangohia te 18 mai i ngā taha e rua.
5x=-15
Tangohia te 18 i te 3, ka -15.
x=\frac{-15}{5}
Whakawehea ngā taha e rua ki te 5.
x=-3
Whakawehea te -15 ki te 5, kia riro ko -3.
