Tohaina
Kua tāruatia ki te papatopenga
-3c=20-250
Tangohia te 250 mai i ngā taha e rua.
-3c=-230
Tangohia te 250 i te 20, ka -230.
c=\frac{-230}{-3}
Whakawehea ngā taha e rua ki te -3.
c=\frac{230}{3}
Ka taea te hautanga \frac{-230}{-3} te whakamāmā ki te \frac{230}{3} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
