Ngā Upane mō te Whakaoti Whārite Rārangi

Me whakarea ngā taha e rua ki te -\frac{1}{3}.

$$x-\frac{\frac{2\times 3+1}{3}\left(-\frac{3\times 7+1}{7}\right)\left(-\frac{2\times 11+2}{11}\right)}{\frac{1\times 9+1}{9}\left(-\frac{1\times 8+1}{8}\right)\times 1.6}=6\left(-\frac{1}{3}\right)$$

Tāpirihia te 22 ki te 2, ka 24.

$$x-\frac{-\frac{22}{3}\left(-\frac{24}{11}\right)}{\frac{1\times 9+1}{9}\left(-\frac{1\times 8+1}{8}\right)\times 1.6}=6\left(-\frac{1}{3}\right)$$

Me whakarea te -\frac{22}{3} ki te -\frac{24}{11} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x-\frac{\frac{-22\left(-24\right)}{3\times 11}}{\frac{1\times 9+1}{9}\left(-\frac{1\times 8+1}{8}\right)\times 1.6}=6\left(-\frac{1}{3}\right)$$

Mahia ngā whakarea i roto i te hautanga \frac{-22\left(-24\right)}{3\times 11}.

$$x-\frac{\frac{528}{33}}{\frac{1\times 9+1}{9}\left(-\frac{1\times 8+1}{8}\right)\times 1.6}=6\left(-\frac{1}{3}\right)$$

Whakawehea te 528 ki te 33, kia riro ko 16.

$$x-\frac{16}{\frac{1\times 9+1}{9}\left(-\frac{1\times 8+1}{8}\right)\times 1.6}=6\left(-\frac{1}{3}\right)$$

Whakareatia te 1 ki te 9, ka 9.

$$x-\frac{16}{\frac{9+1}{9}\left(-\frac{1\times 8+1}{8}\right)\times 1.6}=6\left(-\frac{1}{3}\right)$$

Tāpirihia te 9 ki te 1, ka 10.

$$x-\frac{16}{\frac{10}{9}\left(-\frac{1\times 8+1}{8}\right)\times 1.6}=6\left(-\frac{1}{3}\right)$$

Whakareatia te 1 ki te 8, ka 8.

$$x-\frac{16}{\frac{10}{9}\left(-\frac{8+1}{8}\right)\times 1.6}=6\left(-\frac{1}{3}\right)$$

Tāpirihia te 8 ki te 1, ka 9.

$$x-\frac{16}{\frac{10}{9}\left(-\frac{9}{8}\right)\times 1.6}=6\left(-\frac{1}{3}\right)$$

Me whakarea te \frac{10}{9} ki te -\frac{9}{8} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x-\frac{16}{\frac{10\left(-9\right)}{9\times 8}\times 1.6}=6\left(-\frac{1}{3}\right)$$

Mahia ngā whakarea i roto i te hautanga \frac{10\left(-9\right)}{9\times 8}.

$$x-\frac{16}{\frac{-90}{72}\times 1.6}=6\left(-\frac{1}{3}\right)$$

Whakahekea te hautanga \frac{-90}{72} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 18.

$$x-\frac{16}{-\frac{5}{4}\times 1.6}=6\left(-\frac{1}{3}\right)$$

Me tahuri ki tau ā-ira 1.6 ki te hautau \frac{16}{10}. Whakahekea te hautanga \frac{16}{10} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x-\frac{16}{-\frac{5}{4}\times \frac{8}{5}}=6\left(-\frac{1}{3}\right)$$

Me whakarea te -\frac{5}{4} ki te \frac{8}{5} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x-\frac{16}{\frac{-5\times 8}{4\times 5}}=6\left(-\frac{1}{3}\right)$$

Mahia ngā whakarea i roto i te hautanga \frac{-5\times 8}{4\times 5}.

$$x-\frac{16}{\frac{-40}{20}}=6\left(-\frac{1}{3}\right)$$

Whakawehea te -40 ki te 20, kia riro ko -2.

$$x-\frac{16}{-2}=6\left(-\frac{1}{3}\right)$$

Whakawehea te 16 ki te -2, kia riro ko -8.

$$x-\left(-8\right)=6\left(-\frac{1}{3}\right)$$

Ko te tauaro o -8 ko 8.

$$x+8=6\left(-\frac{1}{3}\right)$$

Tuhia te 6\left(-\frac{1}{3}\right) hei hautanga kotahi.

$$x+8=\frac{6\left(-1\right)}{3}$$

Whakareatia te 6 ki te -1, ka -6.

$$x+8=\frac{-6}{3}$$

Whakawehea te -6 ki te 3, kia riro ko -2.
