Kua tāruatia ki te papatopenga
3\times 14=2x
Me whakarea ngā taha e rua o te whārite ki te 240, arā, te tauraro pātahi he tino iti rawa te kitea o 80,120.
42=2x
Whakareatia te 3 ki te 14, ka 42.
2x=42
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{42}{2}
Whakawehea ngā taha e rua ki te 2.
x=21
Whakawehea te 42 ki te 2, kia riro ko 21.
