0.05y-15=105-0.1y
Whakamahia te āhuatanga tohatoha hei whakarea te 0.05 ki te y-300.
0.05y-15+0.1y=105
Me tāpiri te 0.1y ki ngā taha e rua.
0.15y-15=105
Pahekotia te 0.05y me 0.1y, ka 0.15y.
0.15y=105+15
Me tāpiri te 15 ki ngā taha e rua.
0.15y=120
Tāpirihia te 105 ki te 15, ka 120.
y=\frac{120}{0.15}
Whakawehea ngā taha e rua ki te 0.15.
y=\frac{12000}{15}
Whakarohaina te \frac{120}{0.15} mā te whakarea i te taurunga me te tauraro ki te 100.
y=800
Whakawehea te 12000 ki te 15, kia riro ko 800.
