Kua tāruatia ki te papatopenga
12x+24=4704x
Whakareatia te 42 ki te 112, ka 4704.
12x+24-4704x=0
Tangohia te 4704x mai i ngā taha e rua.
-4692x+24=0
Pahekotia te 12x me -4704x, ka -4692x.
-4692x=-24
Tangohia te 24 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-24}{-4692}
Whakawehea ngā taha e rua ki te -4692.
x=\frac{2}{391}
Whakahekea te hautanga \frac{-24}{-4692} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -12.
