3+x-10x=0
Tangohia te 10x mai i ngā taha e rua.
3-9x=0
Pahekotia te x me -10x, ka -9x.
-9x=-3
Tangohia te 3 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-3}{-9}
Whakawehea ngā taha e rua ki te -9.
x=\frac{1}{3}
Whakahekea te hautanga \frac{-3}{-9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -3.
