Whakaoti i te {l}{2*{(x+4)}=30}{y=x}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 2 \cdot {(x + 4)} = 30 }\\ { y = x }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=11$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakawehea ngā taha e rua ki te 2.

$$x+4=\frac{30}{2}$$

Whakawehea te 30 ki te 2, kia riro ko 15.

$$x+4=15$$

Tangohia te 4 mai i ngā taha e rua.

$$x=15-4$$

Tangohia te 4 i te 15, ka 11.

$$x=11$$

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

$$y=11$$

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

$$z=11$$

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

$$a=11$$

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

$$b=11$$

Kua oti te pūnaha te whakatau.

$$x=11 y=11 z=11 a=11 b=11$$
