Tohaina
Kua tāruatia ki te papatopenga
-5=\frac{5\times 8}{4}+b
Tuhia te \frac{5}{4}\times 8 hei hautanga kotahi.
-5=\frac{40}{4}+b
Whakareatia te 5 ki te 8, ka 40.
-5=10+b
Whakawehea te 40 ki te 4, kia riro ko 10.
10+b=-5
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
b=-5-10
Tangohia te 10 mai i ngā taha e rua.
b=-15
Tangohia te 10 i te -5, ka -15.
