Kua tāruatia ki te papatopenga
x=2.5-2.5x
Whakamahia te āhuatanga tohatoha hei whakarea te 2.5 ki te 1-x.
x+2.5x=2.5
Me tāpiri te 2.5x ki ngā taha e rua.
3.5x=2.5
Pahekotia te x me 2.5x, ka 3.5x.
x=\frac{2.5}{3.5}
Whakawehea ngā taha e rua ki te 3.5.
x=\frac{25}{35}
Whakarohaina te \frac{2.5}{3.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{5}{7}
Whakahekea te hautanga \frac{25}{35} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
