Tohaina
Kua tāruatia ki te papatopenga
3c+45+4c=3
Me tāpiri te 4c ki ngā taha e rua.
7c+45=3
Pahekotia te 3c me 4c, ka 7c.
7c=3-45
Tangohia te 45 mai i ngā taha e rua.
7c=-42
Tangohia te 45 i te 3, ka -42.
c=\frac{-42}{7}
Whakawehea ngā taha e rua ki te 7.
c=-6
Whakawehea te -42 ki te 7, kia riro ko -6.
