Kua tāruatia ki te papatopenga
5v-32>-18+12v
Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te 6-4v.
5v-32-12v>-18
Tangohia te 12v mai i ngā taha e rua.
-7v-32>-18
Pahekotia te 5v me -12v, ka -7v.
-7v>-18+32
Me tāpiri te 32 ki ngā taha e rua.
-7v>14
Tāpirihia te -18 ki te 32, ka 14.
v<\frac{14}{-7}
Whakawehea ngā taha e rua ki te -7. I te mea he tōraro a -7, ka huri te ahunga koreōrite.
v<-2
Whakawehea te 14 ki te -7, kia riro ko -2.
