Kua tāruatia ki te papatopenga
-2c+4-2=0
Pahekotia te c me -3c, ka -2c.
-2c+2=0
Tangohia te 2 i te 4, ka 2.
-2c=-2
Tangohia te 2 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
c=\frac{-2}{-2}
Whakawehea ngā taha e rua ki te -2.
c=1
Whakawehea te -2 ki te -2, kia riro ko 1.
