10x-4-120x=0
Tangohia te 120x mai i ngā taha e rua.
-110x-4=0
Pahekotia te 10x me -120x, ka -110x.
-110x=4
Me tāpiri te 4 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x=\frac{4}{-110}
Whakawehea ngā taha e rua ki te -110.
x=-\frac{2}{55}
Whakahekea te hautanga \frac{4}{-110} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
