3+0.25x=\frac{4}{0.5}
Whakawehea ngā taha e rua ki te 0.5.
3+0.25x=\frac{40}{5}
Whakarohaina te \frac{4}{0.5} mā te whakarea i te taurunga me te tauraro ki te 10.
3+0.25x=8
Whakawehea te 40 ki te 5, kia riro ko 8.
0.25x=8-3
Tangohia te 3 mai i ngā taha e rua.
0.25x=5
Tangohia te 3 i te 8, ka 5.
x=\frac{5}{0.25}
Whakawehea ngā taha e rua ki te 0.25.
x=\frac{500}{25}
Whakarohaina te \frac{5}{0.25} mā te whakarea i te taurunga me te tauraro ki te 100.
x=20
Whakawehea te 500 ki te 25, kia riro ko 20.
