Whakaoti i te {l}{z=2}{a={(8/2)}+{(6/2)}*{(40/7)}}{b=a}{text{Solvefor}ctext{where}}{c=b}

$$\left. \begin{array} { l } { z = 2 }\\ { a = {(\frac{8}{2})} + {(\frac{6}{2})} \cdot {(\frac{40}{7})} }\\ { b = a }\\ { \text{Solve for } c \text{ where} } \\ { c = b } \end{array} \right.$$

Whakaoti mō z, a, b, c

$$c = \frac{148}{7} = 21\frac{1}{7} \approx 21.142857143$$

Whakaarohia te whārite tuarua. Whakawehea te 8 ki te 2, kia riro ko 4.

$$a=4+\frac{6}{2}\times \frac{40}{7}$$

Whakawehea te 6 ki te 2, kia riro ko 3.

$$a=4+3\times \frac{40}{7}$$

Whakareatia te 3 ki te \frac{40}{7}, ka \frac{120}{7}.

$$a=4+\frac{120}{7}$$

Tāpirihia te 4 ki te \frac{120}{7}, ka \frac{148}{7}.

$$a=\frac{148}{7}$$

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

$$b=\frac{148}{7}$$

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

$$c=\frac{148}{7}$$

Kua oti te pūnaha te whakatau.

$$z=2 a=\frac{148}{7} b=\frac{148}{7} c=\frac{148}{7}$$
