Kua tāruatia ki te papatopenga
x\times 5=Vxy-V
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te Vx, arā, te tauraro pātahi he tino iti rawa te kitea o V,x.
x\times 5-Vxy=-V
Tangohia te Vxy mai i ngā taha e rua.
-Vxy+5x=-V
Whakaraupapatia anō ngā kīanga tau.
\left(-Vy+5\right)x=-V
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\left(5-Vy\right)x=-V
He hanga arowhānui tō te whārite.
\frac{\left(5-Vy\right)x}{5-Vy}=-\frac{V}{5-Vy}
Whakawehea ngā taha e rua ki te 5-Vy.
x=-\frac{V}{5-Vy}
Mā te whakawehe ki te 5-Vy ka wetekia te whakareanga ki te 5-Vy.
x=-\frac{V}{5-Vy}\text{, }x\neq 0
Tē taea kia ōrite te tāupe x ki 0.
