Whakaoti i te {l}{9{(x)}=3}{y=-5x-24}{text{Solvefor}ztext{where}}{z=y}

$$\left. \begin{array} { l } { 9 {(x)} = 3 }\\ { y = -5 x - 24 }\\ { \text{Solve for } z \text{ where} } \\ { z = y } \end{array} \right.$$

Whakaoti mō x, y, z

$$z = -\frac{77}{3} = -25\frac{2}{3} \approx -25.666666667$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakawehea ngā taha e rua ki te 9.

$$x=\frac{3}{9}$$

Whakahekea te hautanga \frac{3}{9} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$x=\frac{1}{3}$$

Whakaarohia te whārite tuarua. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$y=-5\times \frac{1}{3}-24$$

Whakareatia te -5 ki te \frac{1}{3}, ka -\frac{5}{3}.

$$y=-\frac{5}{3}-24$$

Tangohia te 24 i te -\frac{5}{3}, ka -\frac{77}{3}.

$$y=-\frac{77}{3}$$

Whakaarohia te whārite tuatoru. Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$z=-\frac{77}{3}$$

Kua oti te pūnaha te whakatau.

$$x=\frac{1}{3} y=-\frac{77}{3} z=-\frac{77}{3}$$
