Kua tāruatia ki te papatopenga
0.5x=35-20
Tangohia te 20 mai i ngā taha e rua.
0.5x=15
Tangohia te 20 i te 35, ka 15.
x=\frac{15}{0.5}
Whakawehea ngā taha e rua ki te 0.5.
x=\frac{150}{5}
Whakarohaina te \frac{15}{0.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x=30
Whakawehea te 150 ki te 5, kia riro ko 30.
