Tohaina
Kua tāruatia ki te papatopenga
4r+2-r=0
Tangohia te r mai i ngā taha e rua.
3r+2=0
Pahekotia te 4r me -r, ka 3r.
3r=-2
Tangohia te 2 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
r=\frac{-2}{3}
Whakawehea ngā taha e rua ki te 3.
r=-\frac{2}{3}
Ka taea te hautanga \frac{-2}{3} te tuhi anō ko -\frac{2}{3} mā te tango i te tohu tōraro.
