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

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

Whakaoti mō x, y, z, a, b

$$b=1$$

Whakaarohia te whārite tuatahi. Pahekotia te x me x, ka 2x.

$$2=2x$$

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

$$2x=2$$

Whakawehea ngā taha e rua ki te 2.

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

Whakawehea te 2 ki te 2, kia riro ko 1.

$$x=1$$

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

$$y=1$$

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

$$z=1$$

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

$$a=1$$

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

$$b=1$$

Kua oti te pūnaha te whakatau.

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