Whakaoti i te {l}{2+2/x=3*3/x}{y=x}{z=-5}{a=y}{b=z}{text{Solvefor}c,dtext{where}}{c=a}{d=b}

$$\left. \begin{array} { l } { 2 + 2 / x = 3 \cdot 3 / x }\\ { y = x }\\ { z = -5 }\\ { a = y }\\ { b = z }\\ { \text{Solve for } c,d \text{ where} } \\ { c = a }\\ { d = b } \end{array} \right.$$

Whakaoti mō x, y, z, a, b, c, d

$$c = \frac{7}{2} = 3\frac{1}{2} = 3.5$$

$$d=-5$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.

$$x\times 2+2=3\times 3$$

Whakareatia te 3 ki te 3, ka 9.

$$x\times 2+2=9$$

Tangohia te 2 mai i ngā taha e rua.

$$x\times 2=9-2$$

Tangohia te 2 i te 9, ka 7.

$$x\times 2=7$$

Whakawehea ngā taha e rua ki te 2.

$$x=\frac{7}{2}$$

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

$$y=\frac{7}{2}$$

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

$$a=\frac{7}{2}$$

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

$$c=\frac{7}{2}$$

Kua oti te pūnaha te whakatau.

$$x=\frac{7}{2} y=\frac{7}{2} z=-5 a=\frac{7}{2} b=-5 c=\frac{7}{2} d=-5$$
