Kua tāruatia ki te papatopenga
2x=3\times 0.005
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 3x, arā, te tauraro pātahi he tino iti rawa te kitea o 3,x.
2x=0.015
Whakareatia te 3 ki te 0.005, ka 0.015.
x=\frac{0.015}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{15}{2000}
Whakarohaina te \frac{0.015}{2} mā te whakarea i te taurunga me te tauraro ki te 1000.
x=\frac{3}{400}
Whakahekea te hautanga \frac{15}{2000} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
