Kua tāruatia ki te papatopenga
4c+18=c
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2c+9.
4c+18-c=0
Tangohia te c mai i ngā taha e rua.
3c+18=0
Pahekotia te 4c me -c, ka 3c.
3c=-18
Tangohia te 18 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
c=\frac{-18}{3}
Whakawehea ngā taha e rua ki te 3.
c=-6
Whakawehea te -18 ki te 3, kia riro ko -6.
