$$\left. \begin{array} { l } { w = 3.5 }\\ { x = -9 }\\ { y = -12.4 }\\ { z = w - x + y }\\ { a = z }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

Whakaoti mō w, x, y, z, a, b, c, d

$$d=0.1$$

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

$$z=3.5-\left(-9\right)-12.4$$

Whakareatia te -1 ki te -9, ka 9.

$$z=3.5+9-12.4$$

Tāpirihia te 3.5 ki te 9, ka 12.5.

$$z=12.5-12.4$$

Tangohia te 12.4 i te 12.5, ka 0.1.

$$z=0.1$$

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

$$a=0.1$$

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

$$b=0.1$$

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

$$c=0.1$$

Whakaarohia te whārite (8). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$d=0.1$$

Kua oti te pūnaha te whakatau.

$$w=3.5 x=-9 y=-12.4 z=0.1 a=0.1 b=0.1 c=0.1 d=0.1$$
