Whakaoti i te {l}{9a+b-8c=0}{a+b-2c=0}{8a+2b-2c=0}

$$\left. \begin{array} { l } { 9 a + b - 8 c = 0 } \\ { a + b - 2 c = 0 } \\ { 8 a + 2 b - 2 c = 0 } \end{array} \right.$$

Whakaoti mō a, b, c

$$a=0$$

$$b=0$$

$$c=0$$

Ngā Hipanga Poto E Whakamahi Whakakapinga Ana

Me whakaoti te 9a+b-8c=0 mō b.

$$b=-9a+8c$$

Whakakapia te -9a+8c mō te b i te whārite tuarua me te tuatoru.

$$a-9a+8c-2c=0 8a+2\left(-9a+8c\right)-2c=0$$

Me whakaoti ēnei whārite mō a me c takitahi.

$$a=\frac{3}{4}c c=\frac{5}{7}a$$

Whakakapia te \frac{3}{4}c mō te a i te whārite c=\frac{5}{7}a.

$$c=\frac{5}{7}\times \frac{3}{4}c$$

Me whakaoti te c=\frac{5}{7}\times \frac{3}{4}c mō c.

$$c=0$$

Whakakapia te 0 mō te c i te whārite a=\frac{3}{4}c.

$$a=\frac{3}{4}\times 0$$

Tātaitia te a i te a=\frac{3}{4}\times 0.

$$a=0$$

Whakakapia te 0 mō te a me te 0 mō c i te whārite b=-9a+8c.

$$b=-9\times 0+8\times 0$$

Tātaitia te b i te b=-9\times 0+8\times 0.

$$b=0$$

Kua oti te pūnaha te whakatau.

$$a=0 b=0 c=0$$
