Whakaoti i te 3x-6(x/2+1/3)-4(x-1)

$$3 x - 6 ( \frac { x } { 2 } + \frac { 1 } { 3 } ) - 4 ( x - 1 )$$

Aromātai

$$2-4x$$

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}.

$$3x-6\left(\frac{3x}{6}+\frac{2}{6}\right)-4\left(x-1\right)$$

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.

$$3x-6\times \frac{3x+2}{6}-4\left(x-1\right)$$

Me whakakore te 6 me te 6.

$$3x-\left(3x+2\right)-4\left(x-1\right)$$

Hei kimi i te tauaro o 3x+2, kimihia te tauaro o ia taurangi.

$$3x-3x-2-4\left(x-1\right)$$

Pahekotia te 3x me -3x, ka 0.

$$-2-4\left(x-1\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te x-1.

$$-2-4x+4$$

Tāpirihia te -2 ki te 4, ka 2.
