0.16x=0.16\left(0.96-x\right)
Pahekotia te 0.28x me -0.12x, ka 0.16x.
0.16x=0.1536-0.16x
Whakamahia te āhuatanga tohatoha hei whakarea te 0.16 ki te 0.96-x.
0.16x+0.16x=0.1536
Me tāpiri te 0.16x ki ngā taha e rua.
0.32x=0.1536
Pahekotia te 0.16x me 0.16x, ka 0.32x.
x=\frac{0.1536}{0.32}
Whakawehea ngā taha e rua ki te 0.32.
x=\frac{1536}{3200}
Whakarohaina te \frac{0.1536}{0.32} mā te whakarea i te taurunga me te tauraro ki te 10000.
x=\frac{12}{25}
Whakahekea te hautanga \frac{1536}{3200} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 128.
