Kua tāruatia ki te papatopenga
8x\times \frac{1}{8}+8x\times \frac{1}{8}=8\times \frac{1}{16}
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 8x, arā, te tauraro pātahi he tino iti rawa te kitea o 8,x.
x+8x\times \frac{1}{8}=8\times \frac{1}{16}
Me whakakore te 8 me te 8.
x+x=8\times \frac{1}{16}
Me whakakore te 8 me te 8.
2x=8\times \frac{1}{16}
Pahekotia te x me x, ka 2x.
2x=\frac{8}{16}
Whakareatia te 8 ki te \frac{1}{16}, ka \frac{8}{16}.
2x=\frac{1}{2}
Whakahekea te hautanga \frac{8}{16} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 8.
x=\frac{\frac{1}{2}}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{1}{2\times 2}
Tuhia te \frac{\frac{1}{2}}{2} hei hautanga kotahi.
x=\frac{1}{4}
Whakareatia te 2 ki te 2, ka 4.
