300+2\times 450=3x
Whakareatia te 1.5 ki te 200, ka 300.
300+900=3x
Whakareatia te 2 ki te 450, ka 900.
1200=3x
Tāpirihia te 300 ki te 900, ka 1200.
3x=1200
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=\frac{1200}{3}
Whakawehea ngā taha e rua ki te 3.
x=400
Whakawehea te 1200 ki te 3, kia riro ko 400.
