Kua tāruatia ki te papatopenga
15v+25=v
Whakamahia te āhuatanga tohatoha hei whakarea te 3v+5 ki te 5.
15v+25-v=0
Tangohia te v mai i ngā taha e rua.
14v+25=0
Pahekotia te 15v me -v, ka 14v.
14v=-25
Tangohia te 25 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
v=\frac{-25}{14}
Whakawehea ngā taha e rua ki te 14.
v=-\frac{25}{14}
Ka taea te hautanga \frac{-25}{14} te tuhi anō ko -\frac{25}{14} mā te tango i te tohu tōraro.
