Whakaoti mō b
b=12
Tohaina
Kua tāruatia ki te papatopenga
6=\frac{-12}{2}+b
Tuhia te -\frac{1}{2}\times 12 hei hautanga kotahi.
6=-6+b
Whakawehea te -12 ki te 2, kia riro ko -6.
-6+b=6
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
b=6+6
Me tāpiri te 6 ki ngā taha e rua.
b=12
Tāpirihia te 6 ki te 6, ka 12.
