Kua tāruatia ki te papatopenga
19.5x-8.3=10.7
Whakareatia te 3.9 ki te 5, ka 19.5.
19.5x=10.7+8.3
Me tāpiri te 8.3 ki ngā taha e rua.
19.5x=19
Tāpirihia te 10.7 ki te 8.3, ka 19.
x=\frac{19}{19.5}
Whakawehea ngā taha e rua ki te 19.5.
x=\frac{190}{195}
Whakarohaina te \frac{19}{19.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{38}{39}
Whakahekea te hautanga \frac{190}{195} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
