Kua tāruatia ki te papatopenga
7+3x+15x=9
Me tāpiri te 15x ki ngā taha e rua.
7+18x=9
Pahekotia te 3x me 15x, ka 18x.
18x=9-7
Tangohia te 7 mai i ngā taha e rua.
18x=2
Tangohia te 7 i te 9, ka 2.
x=\frac{2}{18}
Whakawehea ngā taha e rua ki te 18.
x=\frac{1}{9}
Whakahekea te hautanga \frac{2}{18} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
