Tohaina
Kua tāruatia ki te papatopenga
8-x+15x=42
Me tāpiri te 15x ki ngā taha e rua.
8+14x=42
Pahekotia te -x me 15x, ka 14x.
14x=42-8
Tangohia te 8 mai i ngā taha e rua.
14x=34
Tangohia te 8 i te 42, ka 34.
x=\frac{34}{14}
Whakawehea ngā taha e rua ki te 14.
x=\frac{17}{7}
Whakahekea te hautanga \frac{34}{14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
