Kua tāruatia ki te papatopenga
5\times 16=4x
Me whakarea ngā taha e rua o te whārite ki te 120, arā, te tauraro pātahi he tino iti rawa te kitea o 24,30.
80=4x
Whakareatia te 5 ki te 16, ka 80.
4x=80
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{80}{4}
Whakawehea ngā taha e rua ki te 4.
x=20
Whakawehea te 80 ki te 4, kia riro ko 20.
