Tohaina
Kua tāruatia ki te papatopenga
zx=y\times 4
Me whakarea ngā taha e rua o te whārite ki te yz, arā, te tauraro pātahi he tino iti rawa te kitea o y,z.
zx=4y
He hanga arowhānui tō te whārite.
\frac{zx}{z}=\frac{4y}{z}
Whakawehea ngā taha e rua ki te z.
x=\frac{4y}{z}
Mā te whakawehe ki te z ka wetekia te whakareanga ki te z.
zx=y\times 4
Tē taea kia ōrite te tāupe y ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te yz, arā, te tauraro pātahi he tino iti rawa te kitea o y,z.
y\times 4=zx
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
4y=xz
He hanga arowhānui tō te whārite.
\frac{4y}{4}=\frac{xz}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{xz}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=\frac{xz}{4}\text{, }y\neq 0
Tē taea kia ōrite te tāupe y ki 0.
