Kua tāruatia ki te papatopenga
x=75+0.75x
Whakamahia te āhuatanga tohatoha hei whakarea te 100+x ki te 0.75.
x-0.75x=75
Tangohia te 0.75x mai i ngā taha e rua.
0.25x=75
Pahekotia te x me -0.75x, ka 0.25x.
x=\frac{75}{0.25}
Whakawehea ngā taha e rua ki te 0.25.
x=\frac{7500}{25}
Whakarohaina te \frac{75}{0.25} mā te whakarea i te taurunga me te tauraro ki te 100.
x=300
Whakawehea te 7500 ki te 25, kia riro ko 300.
