Kua tāruatia ki te papatopenga
-1-0.5x=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-0.5x=y+1
Me tāpiri te 1 ki ngā taha e rua.
\frac{-0.5x}{-0.5}=\frac{y+1}{-0.5}
Me whakarea ngā taha e rua ki te -2.
x=\frac{y+1}{-0.5}
Mā te whakawehe ki te -0.5 ka wetekia te whakareanga ki te -0.5.
x=-2y-2
Whakawehe y+1 ki te -0.5 mā te whakarea y+1 ki te tau huripoki o -0.5.
