Whakaoti i te {l}{100=10x}{y=--20x}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 100 = 10 x }\\ { y = --20 x }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=200$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakawehea ngā taha e rua ki te 10.

$$\frac{100}{10}=x$$

Whakawehea te 100 ki te 10, kia riro ko 10.

$$10=x$$

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

$$x=10$$

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

$$y=\left(-\left(-20\right)\right)\times 10$$

Ko te tauaro o -20 ko 20.

$$y=20\times 10$$

Whakareatia te 20 ki te 10, ka 200.

$$y=200$$

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

$$z=200$$

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

$$a=200$$

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

$$b=200$$

Kua oti te pūnaha te whakatau.

$$x=10 y=200 z=200 a=200 b=200$$
