$$\left. \begin{array} { l } { 4 \cdot 35 = {(x \cdot 5)} + {(x \cdot 30)} }\\ { y = x }\\ { z = y }\\ { \text{Solve for } a \text{ where} } \\ { a = z } \end{array} \right.$$

Whakaoti mō x, y, z, a

$$a=4$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakareatia te 4 ki te 35, ka 140.

$$140=x\times 5+x\times 30$$

Pahekotia te x\times 5 me x\times 30, ka 35x.

$$140=35x$$

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

$$35x=140$$

Whakawehea ngā taha e rua ki te 35.

$$x=\frac{140}{35}$$

Whakawehea te 140 ki te 35, kia riro ko 4.

$$x=4$$

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

$$y=4$$

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

$$z=4$$

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

$$a=4$$

Kua oti te pūnaha te whakatau.

$$x=4 y=4 z=4 a=4$$
