6c+14=4c+4
Pahekotia te -5c me 9c, ka 4c.
6c+14-4c=4
Tangohia te 4c mai i ngā taha e rua.
2c+14=4
Pahekotia te 6c me -4c, ka 2c.
2c=4-14
Tangohia te 14 mai i ngā taha e rua.
2c=-10
Tangohia te 14 i te 4, ka -10.
c=\frac{-10}{2}
Whakawehea ngā taha e rua ki te 2.
c=-5
Whakawehea te -10 ki te 2, kia riro ko -5.
