Kua tāruatia ki te papatopenga
5\times 28=2x
Me whakarea ngā taha e rua o te whārite ki te 200, arā, te tauraro pātahi he tino iti rawa te kitea o 40,100.
140=2x
Whakareatia te 5 ki te 28, ka 140.
2x=140
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{140}{2}
Whakawehea ngā taha e rua ki te 2.
x=70
Whakawehea te 140 ki te 2, kia riro ko 70.
