Kua tāruatia ki te papatopenga
4x=y+2
Me whakarea ngā taha e rua o te whārite ki te 4\left(y+2\right), arā, te tauraro pātahi he tino iti rawa te kitea o y+2,4.
\frac{4x}{4}=\frac{y+2}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{y+2}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=\frac{y}{4}+\frac{1}{2}
Whakawehe y+2 ki te 4.
4x=y+2
Tē taea kia ōrite te tāupe y ki -2 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 4\left(y+2\right), arā, te tauraro pātahi he tino iti rawa te kitea o y+2,4.
y+2=4x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
y=4x-2
Tangohia te 2 mai i ngā taha e rua.
y=4x-2\text{, }y\neq -2
Tē taea kia ōrite te tāupe y ki -2.
