Whakaoti mō V_1, V_2, V_0

$$V_{1} = \frac{630}{11} = 57\frac{3}{11} \approx 57.272727273$$

$$V_{2} = \frac{1780}{11} = 161\frac{9}{11} \approx 161.818181818$$

$$V_{0} = -\frac{520}{11} = -47\frac{3}{11} \approx -47.272727273$$

Ngā Hipanga Poto E Whakamahi Whakakapinga Ana

Me whakarea ia whārite mā te taurea pātahi iti rawa o ngā tauraro kei roto. Whakarūnātia.

$$-420-52V_{1}+21V_{2}=0 30+V_{1}-2V_{2}-5V_{0}=0 V_{1}+V_{0}=10$$

Me raupapa anō ngā whārite.

$$30+V_{1}-2V_{2}-5V_{0}=0 -420-52V_{1}+21V_{2}=0 V_{1}+V_{0}=10$$

Me whakaoti te 30+V_{1}-2V_{2}-5V_{0}=0 mō V_{1}.

$$V_{1}=-30+2V_{2}+5V_{0}$$

Whakakapia te -30+2V_{2}+5V_{0} mō te V_{1} i te whārite tuarua me te tuatoru.

$$-420-52\left(-30+2V_{2}+5V_{0}\right)+21V_{2}=0 -30+2V_{2}+5V_{0}+V_{0}=10$$

Me whakaoti ēnei whārite mō V_{2} me V_{0} takitahi.

$$V_{2}=\frac{1140}{83}-\frac{260}{83}V_{0} V_{0}=\frac{20}{3}-\frac{1}{3}V_{2}$$

Whakakapia te \frac{1140}{83}-\frac{260}{83}V_{0} mō te V_{2} i te whārite V_{0}=\frac{20}{3}-\frac{1}{3}V_{2}.

$$V_{0}=\frac{20}{3}-\frac{1}{3}\left(\frac{1140}{83}-\frac{260}{83}V_{0}\right)$$

Me whakaoti te V_{0}=\frac{20}{3}-\frac{1}{3}\left(\frac{1140}{83}-\frac{260}{83}V_{0}\right) mō V_{0}.

$$V_{0}=-\frac{520}{11}$$

Whakakapia te -\frac{520}{11} mō te V_{0} i te whārite V_{2}=\frac{1140}{83}-\frac{260}{83}V_{0}.

$$V_{2}=\frac{1140}{83}-\frac{260}{83}\left(-\frac{520}{11}\right)$$

Tātaitia te V_{2} i te V_{2}=\frac{1140}{83}-\frac{260}{83}\left(-\frac{520}{11}\right).

$$V_{2}=\frac{1780}{11}$$

Whakakapia te \frac{1780}{11} mō te V_{2} me te -\frac{520}{11} mō V_{0} i te whārite V_{1}=-30+2V_{2}+5V_{0}.

$$V_{1}=-30+2\times \frac{1780}{11}+5\left(-\frac{520}{11}\right)$$

Tātaitia te V_{1} i te V_{1}=-30+2\times \frac{1780}{11}+5\left(-\frac{520}{11}\right).

$$V_{1}=\frac{630}{11}$$

Kua oti te pūnaha te whakatau.

$$V_{1}=\frac{630}{11} V_{2}=\frac{1780}{11} V_{0}=-\frac{520}{11}$$
