Kua tāruatia ki te papatopenga
10\times 90=3x
Me whakarea ngā taha e rua o te whārite ki te 300, arā, te tauraro pātahi he tino iti rawa te kitea o 30,100.
900=3x
Whakareatia te 10 ki te 90, ka 900.
3x=900
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{900}{3}
Whakawehea ngā taha e rua ki te 3.
x=300
Whakawehea te 900 ki te 3, kia riro ko 300.
