Kua tāruatia ki te papatopenga
5x=80-x
Pahekotia te x me 4x, ka 5x.
5x+x=80
Me tāpiri te x ki ngā taha e rua.
6x=80
Pahekotia te 5x me x, ka 6x.
x=\frac{80}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{40}{3}
Whakahekea te hautanga \frac{80}{6} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
