Tohaina
Kua tāruatia ki te papatopenga
a+12=42a
Whakareatia ngā taha e rua o te whārite ki te 3.
a+12-42a=0
Tangohia te 42a mai i ngā taha e rua.
-41a+12=0
Pahekotia te a me -42a, ka -41a.
-41a=-12
Tangohia te 12 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
a=\frac{-12}{-41}
Whakawehea ngā taha e rua ki te -41.
a=\frac{12}{41}
Ka taea te hautanga \frac{-12}{-41} te whakamāmā ki te \frac{12}{41} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
