Kua tāruatia ki te papatopenga
1200-x=1200x
Pahekotia te 480x me 720x, ka 1200x.
1200-x-1200x=0
Tangohia te 1200x mai i ngā taha e rua.
1200-1201x=0
Pahekotia te -x me -1200x, ka -1201x.
-1201x=-1200
Tangohia te 1200 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-1200}{-1201}
Whakawehea ngā taha e rua ki te -1201.
x=\frac{1200}{1201}
Ka taea te hautanga \frac{-1200}{-1201} te whakamāmā ki te \frac{1200}{1201} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
