Whakaoti i te {l}{x+4=7}{y=x}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { x + 4 = 7 }\\ { y = x }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=3$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tangohia te 4 mai i ngā taha e rua.

$$x=7-4$$

Tangohia te 4 i te 7, ka 3.

$$x=3$$

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

$$y=3$$

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

$$z=3$$

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

$$a=3$$

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

$$b=3$$

Kua oti te pūnaha te whakatau.

$$x=3 y=3 z=3 a=3 b=3$$
