Tohaina
Kua tāruatia ki te papatopenga
1=3\left(v-1\right)-3
Pahekotia te v me -v, ka 0.
1=3v-3-3
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te v-1.
1=3v-6
Tangohia te 3 i te -3, ka -6.
3v-6=1
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3v=1+6
Me tāpiri te 6 ki ngā taha e rua.
3v=7
Tāpirihia te 1 ki te 6, ka 7.
v=\frac{7}{3}
Whakawehea ngā taha e rua ki te 3.
