Kua tāruatia ki te papatopenga
0.8x-7.5=0.5
Whakareatia te 2.5 ki te 3, ka 7.5.
0.8x=0.5+7.5
Me tāpiri te 7.5 ki ngā taha e rua.
0.8x=8
Tāpirihia te 0.5 ki te 7.5, ka 8.
x=\frac{8}{0.8}
Whakawehea ngā taha e rua ki te 0.8.
x=\frac{80}{8}
Whakarohaina te \frac{8}{0.8} mā te whakarea i te taurunga me te tauraro ki te 10.
x=10
Whakawehea te 80 ki te 8, kia riro ko 10.
