Kua tāruatia ki te papatopenga
-2+x=-2y
Whakareatia ngā taha e rua o te whārite ki te y.
x=-2y+2
Me tāpiri te 2 ki ngā taha e rua.
-2+x=-2y
Tē taea kia ōrite te tāupe y ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te y.
-2y=-2+x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-2y=x-2
He hanga arowhānui tō te whārite.
\frac{-2y}{-2}=\frac{x-2}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{x-2}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=-\frac{x}{2}+1
Whakawehe -2+x ki te -2.
y=-\frac{x}{2}+1\text{, }y\neq 0
Tē taea kia ōrite te tāupe y ki 0.
