Kua tāruatia ki te papatopenga
42=6+8c-12
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te -2c+3.
42=-6+8c
Tangohia te 12 i te 6, ka -6.
-6+8c=42
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
8c=42+6
Me tāpiri te 6 ki ngā taha e rua.
8c=48
Tāpirihia te 42 ki te 6, ka 48.
c=\frac{48}{8}
Whakawehea ngā taha e rua ki te 8.
c=6
Whakawehea te 48 ki te 8, kia riro ko 6.
