Kua tāruatia ki te papatopenga
43=-9v-29
Pahekotia te -3v me -6v, ka -9v.
-9v-29=43
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-9v=43+29
Me tāpiri te 29 ki ngā taha e rua.
-9v=72
Tāpirihia te 43 ki te 29, ka 72.
v=\frac{72}{-9}
Whakawehea ngā taha e rua ki te -9.
v=-8
Whakawehea te 72 ki te -9, kia riro ko -8.
