Kua tāruatia ki te papatopenga
-3=\frac{8\left(-7\right)}{7}+C
Tuhia te \frac{8}{7}\left(-7\right) hei hautanga kotahi.
-3=\frac{-56}{7}+C
Whakareatia te 8 ki te -7, ka -56.
-3=-8+C
Whakawehea te -56 ki te 7, kia riro ko -8.
-8+C=-3
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
C=-3+8
Me tāpiri te 8 ki ngā taha e rua.
C=5
Tāpirihia te -3 ki te 8, ka 5.
