Kua tāruatia ki te papatopenga
3\times 7=7x
Me whakarea ngā taha e rua o te whārite ki te 42, arā, te tauraro pātahi he tino iti rawa te kitea o 14,6.
21=7x
Whakareatia te 3 ki te 7, ka 21.
7x=21
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{21}{7}
Whakawehea ngā taha e rua ki te 7.
x=3
Whakawehea te 21 ki te 7, kia riro ko 3.
