Kua tāruatia ki te papatopenga
0.5x=4.2+0.3
Me tāpiri te 0.3 ki ngā taha e rua.
0.5x=4.5
Tāpirihia te 4.2 ki te 0.3, ka 4.5.
x=\frac{4.5}{0.5}
Whakawehea ngā taha e rua ki te 0.5.
x=\frac{45}{5}
Whakarohaina te \frac{4.5}{0.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x=9
Whakawehea te 45 ki te 5, kia riro ko 9.
