Whakaoti i te {l}{8=2-4x}{y=x}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 8 = 2 - 4 x }\\ { y = x }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b = -\frac{3}{2} = -1\frac{1}{2} = -1.5$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$2-4x=8$$

Tangohia te 2 mai i ngā taha e rua.

$$-4x=8-2$$

Tangohia te 2 i te 8, ka 6.

$$-4x=6$$

Whakawehea ngā taha e rua ki te -4.

$$x=\frac{6}{-4}$$

Whakahekea te hautanga \frac{6}{-4} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=-\frac{3}{2}$$

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

$$y=-\frac{3}{2}$$

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

$$z=-\frac{3}{2}$$

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

$$a=-\frac{3}{2}$$

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

$$b=-\frac{3}{2}$$

Kua oti te pūnaha te whakatau.

$$x=-\frac{3}{2} y=-\frac{3}{2} z=-\frac{3}{2} a=-\frac{3}{2} b=-\frac{3}{2}$$
