Kua tāruatia ki te papatopenga
2.5x-5=170
Pahekotia te x me 1.5x, ka 2.5x.
2.5x=170+5
Me tāpiri te 5 ki ngā taha e rua.
2.5x=175
Tāpirihia te 170 ki te 5, ka 175.
x=\frac{175}{2.5}
Whakawehea ngā taha e rua ki te 2.5.
x=\frac{1750}{25}
Whakarohaina te \frac{175}{2.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x=70
Whakawehea te 1750 ki te 25, kia riro ko 70.
