Whakaoti i te {l}{4x+5=25}{y=x}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 4 x + 5 = 25 }\\ { y = x }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=5$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tangohia te 5 mai i ngā taha e rua.

$$4x=25-5$$

Tangohia te 5 i te 25, ka 20.

$$4x=20$$

Whakawehea ngā taha e rua ki te 4.

$$x=\frac{20}{4}$$

Whakawehea te 20 ki te 4, kia riro ko 5.

$$x=5$$

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

$$y=5$$

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

$$z=5$$

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

$$a=5$$

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

$$b=5$$

Kua oti te pūnaha te whakatau.

$$x=5 y=5 z=5 a=5 b=5$$
