120-0.4p=x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-0.4p=x-120
Tangohia te 120 mai i ngā taha e rua.
\frac{-0.4p}{-0.4}=\frac{x-120}{-0.4}
Whakawehea ngā taha e rua o te whārite ki te -0.4, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
p=\frac{x-120}{-0.4}
Mā te whakawehe ki te -0.4 ka wetekia te whakareanga ki te -0.4.
p=-\frac{5x}{2}+300
Whakawehe x-120 ki te -0.4 mā te whakarea x-120 ki te tau huripoki o -0.4.
