Whakaoti i te {l}{4y+35=2}{9v+2w=7}{3v-8w=-2}

$$\left. \begin{array} { l } { 4 y + 35 = 2 } \\ { 9 v + 2 w = 7 } \\ { 3 v - 8 w = - 2 } \end{array} \right.$$

Whakaoti mō y, v, w

$$y = -\frac{33}{4} = -8\frac{1}{4} = -8.25$$

$$v=\frac{2}{3}\approx 0.666666667$$

$$w=\frac{1}{2}=0.5$$

Ngā Hipanga Poto E Whakamahi Whakakapinga Ana

Me whakaoti te 4y+35=2 mō y.

$$y=-\frac{33}{4}$$

Me whakaoti te whārite tuarua mō v me te whārite tuatoru mō w.

$$v=-\frac{2}{9}w+\frac{7}{9} w=\frac{3}{8}v+\frac{1}{4}$$

Whakakapia te -\frac{2}{9}w+\frac{7}{9} mō te v i te whārite w=\frac{3}{8}v+\frac{1}{4}.

$$w=\frac{3}{8}\left(-\frac{2}{9}w+\frac{7}{9}\right)+\frac{1}{4}$$

Me whakaoti te w=\frac{3}{8}\left(-\frac{2}{9}w+\frac{7}{9}\right)+\frac{1}{4} mō w.

$$w=\frac{1}{2}$$

Whakakapia te \frac{1}{2} mō te w i te whārite v=-\frac{2}{9}w+\frac{7}{9}.

$$v=-\frac{2}{9}\times \frac{1}{2}+\frac{7}{9}$$

Tātaitia te v i te v=-\frac{2}{9}\times \frac{1}{2}+\frac{7}{9}.

$$v=\frac{2}{3}$$

Kua oti te pūnaha te whakatau.

$$y=-\frac{33}{4} v=\frac{2}{3} w=\frac{1}{2}$$
