1100x-120-900x=0
Tangohia te 900x mai i ngā taha e rua.
200x-120=0
Pahekotia te 1100x me -900x, ka 200x.
200x=120
Me tāpiri te 120 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{120}{200}
Whakawehea ngā taha e rua ki te 200.
x=\frac{3}{5}
Whakahekea te hautanga \frac{120}{200} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 40.
