$$\left. \begin{array} { l } { w = 2 }\\ { n = 3 }\\ { x = 7 {(-8 w + 6)} + 5 n }\\ { y = x }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō w, n, x, y, z, a, b

Ngā Upane Otinga

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

$$x=7\left(-8\times 2+6\right)+5\times 3$$

Whakareatia te -8 ki te 2, ka -16.

$$x=7\left(-16+6\right)+5\times 3$$

Tāpirihia te -16 ki te 6, ka -10.

$$x=7\left(-10\right)+5\times 3$$

Whakareatia te 7 ki te -10, ka -70.

$$x=-70+5\times 3$$

Whakareatia te 5 ki te 3, ka 15.

$$x=-70+15$$

Tāpirihia te -70 ki te 15, ka -55.

$$x=-55$$

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

$$y=-55$$

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

$$z=-55$$

Whakaarohia te whārite (6). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$a=-55$$

Whakaarohia te whārite (7). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$b=-55$$

Kua oti te pūnaha te whakatau.

$$w=2 n=3 x=-55 y=-55 z=-55 a=-55 b=-55$$
