Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o 2 me 3 ko 6. Whakareatia \frac{x}{2} ki te \frac{3}{3}. Whakareatia \frac{1}{3} ki te \frac{2}{2}.
3x-6\times \frac{3x+2}{6}-4\left(x-1\right)
Tā te mea he rite te tauraro o \frac{3x}{6} me \frac{2}{6}, me tāpiri rāua mā te tāpiri i ō raua taurunga.
3x-\left(3x+2\right)-4\left(x-1\right)
Me whakakore te 6 me te 6.
3x-3x-2-4\left(x-1\right)
Hei kimi i te tauaro o 3x+2, kimihia te tauaro o ia taurangi.
