0.6x+40-0.4x=50
Whakamahia te āhuatanga tohatoha hei whakarea te 0.4 ki te 100-x.
0.2x+40=50
Pahekotia te 0.6x me -0.4x, ka 0.2x.
0.2x=50-40
Tangohia te 40 mai i ngā taha e rua.
0.2x=10
Tangohia te 40 i te 50, ka 10.
x=\frac{10}{0.2}
Whakawehea ngā taha e rua ki te 0.2.
x=\frac{100}{2}
Whakarohaina te \frac{10}{0.2} mā te whakarea i te taurunga me te tauraro ki te 10.
x=50
Whakawehea te 100 ki te 2, kia riro ko 50.
