9c+7=4c-3
Pahekotia te 8c me -4c, ka 4c.
9c+7-4c=-3
Tangohia te 4c mai i ngā taha e rua.
5c+7=-3
Pahekotia te 9c me -4c, ka 5c.
5c=-3-7
Tangohia te 7 mai i ngā taha e rua.
5c=-10
Tangohia te 7 i te -3, ka -10.
c=\frac{-10}{5}
Whakawehea ngā taha e rua ki te 5.
c=-2
Whakawehea te -10 ki te 5, kia riro ko -2.
