Kua tāruatia ki te papatopenga
4-1.5x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-1.5x=y-4
Tangohia te 4 mai i ngā taha e rua.
\frac{-1.5x}{-1.5}=\frac{y-4}{-1.5}
Whakawehea ngā taha e rua o te whārite ki te -1.5, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{y-4}{-1.5}
Mā te whakawehe ki te -1.5 ka wetekia te whakareanga ki te -1.5.
x=\frac{8-2y}{3}
Whakawehe y-4 ki te -1.5 mā te whakarea y-4 ki te tau huripoki o -1.5.
