Kua tāruatia ki te papatopenga
-7=\frac{7\left(-8\right)}{8}+b
Tuhia te \frac{7}{8}\left(-8\right) hei hautanga kotahi.
-7=\frac{-56}{8}+b
Whakareatia te 7 ki te -8, ka -56.
-7=-7+b
Whakawehea te -56 ki te 8, kia riro ko -7.
-7+b=-7
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
b=-7+7
Me tāpiri te 7 ki ngā taha e rua.
b=0
Tāpirihia te -7 ki te 7, ka 0.
