1x+0.6-0.05x=0.1\times 63
Whakamahia te āhuatanga tohatoha hei whakarea te 0.05 ki te 12-x.
0.95x+0.6=0.1\times 63
Pahekotia te 1x me -0.05x, ka 0.95x.
0.95x+0.6=6.3
Whakareatia te 0.1 ki te 63, ka 6.3.
0.95x=6.3-0.6
Tangohia te 0.6 mai i ngā taha e rua.
0.95x=5.7
Tangohia te 0.6 i te 6.3, ka 5.7.
x=\frac{5.7}{0.95}
Whakawehea ngā taha e rua ki te 0.95.
x=\frac{570}{95}
Whakarohaina te \frac{5.7}{0.95} mā te whakarea i te taurunga me te tauraro ki te 100.
x=6
Whakawehea te 570 ki te 95, kia riro ko 6.
