Kua tāruatia ki te papatopenga
1.04x-x=600
Whakareatia te 1.3 ki te 0.8, ka 1.04.
0.04x=600
Pahekotia te 1.04x me -x, ka 0.04x.
x=\frac{600}{0.04}
Whakawehea ngā taha e rua ki te 0.04.
x=\frac{60000}{4}
Whakarohaina te \frac{600}{0.04} mā te whakarea i te taurunga me te tauraro ki te 100.
x=15000
Whakawehea te 60000 ki te 4, kia riro ko 15000.
