Whakaoti i te {l}{4x-3=25}{y=x}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 4 x - 3 = 25 }\\ { y = x }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=7$$

Whakaarohia te whārite tuatahi. Me tāpiri te 3 ki ngā taha e rua.

$$4x=25+3$$

Tāpirihia te 25 ki te 3, ka 28.

$$4x=28$$

Whakawehea ngā taha e rua ki te 4.

$$x=\frac{28}{4}$$

Whakawehea te 28 ki te 4, kia riro ko 7.

$$x=7$$

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

$$y=7$$

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

$$z=7$$

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

$$a=7$$

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

$$b=7$$

Kua oti te pūnaha te whakatau.

$$x=7 y=7 z=7 a=7 b=7$$
