Kua tāruatia ki te papatopenga
12x-15=21
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
12x=21+15
Me tāpiri te 15 ki ngā taha e rua.
12x=36
Tāpirihia te 21 ki te 15, ka 36.
x=\frac{36}{12}
Whakawehea ngā taha e rua ki te 12.
x=3
Whakawehea te 36 ki te 12, kia riro ko 3.
