Whakaoti i te {l}{2x=4}{y=5x-2}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 2 x = 4 }\\ { y = 5 x - 2 }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=8$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakawehea ngā taha e rua ki te 2.

$$x=\frac{4}{2}$$

Whakawehea te 4 ki te 2, kia riro ko 2.

$$x=2$$

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

$$y=5\times 2-2$$

Whakareatia te 5 ki te 2, ka 10.

$$y=10-2$$

Tangohia te 2 i te 10, ka 8.

$$y=8$$

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

$$z=8$$

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

$$a=8$$

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

$$b=8$$

Kua oti te pūnaha te whakatau.

$$x=2 y=8 z=8 a=8 b=8$$
