Tohaina
Kua tāruatia ki te papatopenga
1500=2b+30
Pahekotia te b me b, ka 2b.
2b+30=1500
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2b=1500-30
Tangohia te 30 mai i ngā taha e rua.
2b=1470
Tangohia te 30 i te 1500, ka 1470.
b=\frac{1470}{2}
Whakawehea ngā taha e rua ki te 2.
b=735
Whakawehea te 1470 ki te 2, kia riro ko 735.
