Kua tāruatia ki te papatopenga
x_{2}x\times 2=14000x
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.
x_{2}x\times 2-14000x=0
Tangohia te 14000x mai i ngā taha e rua.
\left(x_{2}\times 2-14000\right)x=0
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\left(2x_{2}-14000\right)x=0
He hanga arowhānui tō te whārite.
x=0
Whakawehe 0 ki te 2x_{2}-14000.
x\in \emptyset
Tē taea kia ōrite te tāupe x ki 0.
x_{2}x\times 2=14000x
Whakareatia ngā taha e rua o te whārite ki te x.
2xx_{2}=14000x
He hanga arowhānui tō te whārite.
\frac{2xx_{2}}{2x}=\frac{14000x}{2x}
Whakawehea ngā taha e rua ki te 2x.
x_{2}=\frac{14000x}{2x}
Mā te whakawehe ki te 2x ka wetekia te whakareanga ki te 2x.
x_{2}=7000
Whakawehe 14000x ki te 2x.
