17000=500\left(50-x\right)
Tāpirihia te 12000 ki te 5000, ka 17000.
17000=25000-500x
Whakamahia te āhuatanga tohatoha hei whakarea te 500 ki te 50-x.
25000-500x=17000
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-500x=17000-25000
Tangohia te 25000 mai i ngā taha e rua.
-500x=-8000
Tangohia te 25000 i te 17000, ka -8000.
x=\frac{-8000}{-500}
Whakawehea ngā taha e rua ki te -500.
x=16
Whakawehea te -8000 ki te -500, kia riro ko 16.
