Whakaoti i te x(-3/4)-1/6*7/2+1/14*frac{7}{3}

$$x ( - \frac { 3 } { 4 } ) - \frac { 1 } { 6 } \times \frac { 7 } { 2 } + \frac { 1 } { 14 } \times \frac { 7 } { 3 }$$

Aromātai

$$-\frac{3x}{4}-\frac{5}{12}$$

Ngā Upane Otinga

Me whakarea te \frac{1}{6} ki te \frac{7}{2} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x\left(-\frac{3}{4}\right)-\frac{1\times 7}{6\times 2}+\frac{1}{14}\times \frac{7}{3}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 7}{6\times 2}.

$$x\left(-\frac{3}{4}\right)-\frac{7}{12}+\frac{1}{14}\times \frac{7}{3}$$

Me whakarea te \frac{1}{14} ki te \frac{7}{3} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x\left(-\frac{3}{4}\right)-\frac{7}{12}+\frac{1\times 7}{14\times 3}$$

Mahia ngā whakarea i roto i te hautanga \frac{1\times 7}{14\times 3}.

$$x\left(-\frac{3}{4}\right)-\frac{7}{12}+\frac{7}{42}$$

Whakahekea te hautanga \frac{7}{42} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 7.

$$x\left(-\frac{3}{4}\right)-\frac{7}{12}+\frac{1}{6}$$

Ko te maha noa iti rawa atu o 12 me 6 ko 12. Me tahuri -\frac{7}{12} me \frac{1}{6} ki te hautau me te tautūnga 12.

$$x\left(-\frac{3}{4}\right)-\frac{7}{12}+\frac{2}{12}$$

Tā te mea he rite te tauraro o -\frac{7}{12} me \frac{2}{12}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$x\left(-\frac{3}{4}\right)+\frac{-7+2}{12}$$

Tāpirihia te -7 ki te 2, ka -5.

$$x\left(-\frac{3}{4}\right)-\frac{5}{12}$$

Tauwehe

$$\frac{-9x-5}{12}$$

Ngā Upane Otinga

Tauwehea te \frac{1}{12}.

$$\frac{-9x-5}{12}$$

Whakaarohia te -9x-7+2. Whakarea ka paheko i ngā kīanga tau ōrite.

$$-9x-5$$

Me tuhi anō te kīanga whakatauwehe katoa.

$$\frac{-9x-5}{12}$$
