$$\left. \begin{array} { l } { 56 x + 68 x = 90 }\\ { y = x }\\ { z = y }\\ { a = z }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

Whakaoti mō x, y, z, a, b, c, d

$$d=\frac{45}{62}\approx 0.725806452$$

Whakaarohia te whārite tuatahi. Pahekotia te 56x me 68x, ka 124x.

$$124x=90$$

Whakawehea ngā taha e rua ki te 124.

$$x=\frac{90}{124}$$

Whakahekea te hautanga \frac{90}{124} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x=\frac{45}{62}$$

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

$$y=\frac{45}{62}$$

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

$$z=\frac{45}{62}$$

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

$$a=\frac{45}{62}$$

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

$$b=\frac{45}{62}$$

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

$$c=\frac{45}{62}$$

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

$$d=\frac{45}{62}$$

Kua oti te pūnaha te whakatau.

$$x=\frac{45}{62} y=\frac{45}{62} z=\frac{45}{62} a=\frac{45}{62} b=\frac{45}{62} c=\frac{45}{62} d=\frac{45}{62}$$
