Tohaina
Kua tāruatia ki te papatopenga
3=-8-9\left(-2\right)+b
Tātaihia te -2 mā te pū o 3, kia riro ko -8.
3=-8-\left(-18\right)+b
Whakareatia te 9 ki te -2, ka -18.
3=-8+18+b
Ko te tauaro o -18 ko 18.
3=10+b
Tāpirihia te -8 ki te 18, ka 10.
10+b=3
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
b=3-10
Tangohia te 10 mai i ngā taha e rua.
b=-7
Tangohia te 10 i te 3, ka -7.
