Tohaina
Kua tāruatia ki te papatopenga
11=\frac{50}{25}+b
Whakarohaina te \frac{5}{2.5} mā te whakarea i te taurunga me te tauraro ki te 10.
11=2+b
Whakawehea te 50 ki te 25, kia riro ko 2.
2+b=11
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
b=11-2
Tangohia te 2 mai i ngā taha e rua.
b=9
Tangohia te 2 i te 11, ka 9.
