Whakaoti i te {l}{y*x=20}{x=5}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { y \cdot x = 20 }\\ { x = 5 }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō y, x, z, a, b

$$b=4$$

Ngā Upane Otinga

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

$$y\times 5=20$$

Whakawehea ngā taha e rua ki te 5.

$$y=\frac{20}{5}$$

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

$$y=4$$

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

$$z=4$$

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

$$a=4$$

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

$$b=4$$

Kua oti te pūnaha te whakatau.

$$y=4 x=5 z=4 a=4 b=4$$
