12\left(\frac{x}{6}-\frac{3}{6}\right)-12\left(\frac{x}{4}-2\right)

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Ko te taurea pātahi iti rawa o 6 me 2 ko 6. Whakareatia \frac{1}{2} ki te \frac{3}{3}.

12\times \frac{x-3}{6}-12\left(\frac{x}{4}-2\right)

Tā te mea he rite te tauraro o \frac{x}{6} me \frac{3}{6}, me tango rāua mā te tango i ō raua taurunga.

2\left(x-3\right)-12\left(\frac{x}{4}-2\right)

Whakakorea atu te tauwehe pūnoa nui rawa 6 i roto i te 12 me te 6.

2\left(x-3\right)-12\left(\frac{x}{4}-\frac{2\times 4}{4}\right)

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 2 ki te \frac{4}{4}.

2\left(x-3\right)-12\times \frac{x-2\times 4}{4}

Tā te mea he rite te tauraro o \frac{x}{4} me \frac{2\times 4}{4}, me tango rāua mā te tango i ō raua taurunga.

2\left(x-3\right)-12\times \frac{x-8}{4}

Mahia ngā whakarea i roto o x-2\times 4.

2\left(x-3\right)-3\left(x-8\right)

Whakakorea atu te tauwehe pūnoa nui rawa 4 i roto i te 12 me te 4.

2x-6-3\left(x-8\right)

Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-3.

2x-6-3x+24

Whakamahia te āhuatanga tohatoha hei whakarea te -3 ki te x-8.

-x-6+24

Pahekotia te 2x me -3x, ka -x.

-x+18

Tāpirihia te -6 ki te 24, ka 18.
