0.7x+350=455
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
0.7x=455-350
Tangohia te 350 mai i ngā taha e rua.
0.7x=105
Tangohia te 350 i te 455, ka 105.
x=\frac{105}{0.7}
Whakawehea ngā taha e rua ki te 0.7.
x=\frac{1050}{7}
Whakarohaina te \frac{105}{0.7} mā te whakarea i te taurunga me te tauraro ki te 10.
x=150
Whakawehea te 1050 ki te 7, kia riro ko 150.
