17.5w=185.75-45.75
Tangohia te 45.75 mai i ngā taha e rua.
17.5w=140
Tangohia te 45.75 i te 185.75, ka 140.
w=\frac{140}{17.5}
Whakawehea ngā taha e rua ki te 17.5.
w=\frac{1400}{175}
Whakarohaina te \frac{140}{17.5} mā te whakarea i te taurunga me te tauraro ki te 10.
w=8
Whakawehea te 1400 ki te 175, kia riro ko 8.
