Kua tāruatia ki te papatopenga
-\frac{5}{4}x+2=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-\frac{5}{4}x=y-2
Tangohia te 2 mai i ngā taha e rua.
\frac{-\frac{5}{4}x}{-\frac{5}{4}}=\frac{y-2}{-\frac{5}{4}}
Whakawehea ngā taha e rua o te whārite ki te -\frac{5}{4}, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{y-2}{-\frac{5}{4}}
Mā te whakawehe ki te -\frac{5}{4} ka wetekia te whakareanga ki te -\frac{5}{4}.
x=\frac{8-4y}{5}
Whakawehe y-2 ki te -\frac{5}{4} mā te whakarea y-2 ki te tau huripoki o -\frac{5}{4}.
