Whakaoti i te {l}{x+y=48}{6=y}{z=x+0}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { x + y = 48 }\\ { 6 = y }\\ { z = x + 0 }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=42$$

Ngā Upane Otinga

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

$$y=6$$

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

$$x+6=48$$

Tangohia te 6 mai i ngā taha e rua.

$$x=48-6$$

Tangohia te 6 i te 48, ka 42.

$$x=42$$

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

$$z=42+0$$

Tāpirihia te 42 ki te 0, ka 42.

$$z=42$$

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

$$a=42$$

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

$$b=42$$

Kua oti te pūnaha te whakatau.

$$x=42 y=6 z=42 a=42 b=42$$
