Whakaoti i te {l}{3x+6=9}{y=2xx}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 3 x + 6 = 9 }\\ { y = 2 x x }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=2$$

Whakaarohia te whārite tuatahi. Tangohia te 6 mai i ngā taha e rua.

$$3x=9-6$$

Tangohia te 6 i te 9, ka 3.

$$3x=3$$

Whakawehea ngā taha e rua ki te 3.

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

Whakawehea te 3 ki te 3, kia riro ko 1.

$$x=1$$

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

$$y=2\times 1\times 1$$

Whakareatia te 2 ki te 1, ka 2.

$$y=2\times 1$$

Whakareatia te 2 ki te 1, ka 2.

$$y=2$$

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

$$z=2$$

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

$$a=2$$

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

$$b=2$$

Kua oti te pūnaha te whakatau.

$$x=1 y=2 z=2 a=2 b=2$$
