-\frac{1}{2}x+2=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-\frac{1}{2}x=y-2
Tangohia te 2 mai i ngā taha e rua.
\frac{-\frac{1}{2}x}{-\frac{1}{2}}=\frac{y-2}{-\frac{1}{2}}
Me whakarea ngā taha e rua ki te -2.
x=\frac{y-2}{-\frac{1}{2}}
Mā te whakawehe ki te -\frac{1}{2} ka wetekia te whakareanga ki te -\frac{1}{2}.
x=4-2y
Whakawehe y-2 ki te -\frac{1}{2} mā te whakarea y-2 ki te tau huripoki o -\frac{1}{2}.
