Whakaoti i te {l}{x=3}{x-y=7}{z=x+y}{a=z}{b=a}{c=b}{text{Solvefor}dtext{where}}{d=c}

$$\left. \begin{array} { l } { x = 3 }\\ { x - y = 7 }\\ { z = x + y }\\ { a = z }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

Whakaoti mō x, y, z, a, b, c, d

$$d=-1$$

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

$$3-y=7$$

Tangohia te 3 mai i ngā taha e rua.

$$-y=7-3$$

Tangohia te 3 i te 7, ka 4.

$$-y=4$$

Whakawehea ngā taha e rua ki te -1.

$$y=-4$$

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

$$z=3-4$$

Tangohia te 4 i te 3, ka -1.

$$z=-1$$

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

$$a=-1$$

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

$$b=-1$$

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

$$c=-1$$

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

$$d=-1$$

Kua oti te pūnaha te whakatau.

$$x=3 y=-4 z=-1 a=-1 b=-1 c=-1 d=-1$$
