Whakaoti i te {l}{-17=2z-5}{a=z}{b=a}{c=b}{text{Solvefor}dtext{where}}{d=c}

$$\left. \begin{array} { l } { -17 = 2 z - 5 }\\ { a = z }\\ { b = a }\\ { c = b }\\ { \text{Solve for } d \text{ where} } \\ { d = c } \end{array} \right.$$

Whakaoti mō z, a, b, c, d

$$d=-6$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$2z-5=-17$$

Me tāpiri te 5 ki ngā taha e rua.

$$2z=-17+5$$

Tāpirihia te -17 ki te 5, ka -12.

$$2z=-12$$

Whakawehea ngā taha e rua ki te 2.

$$z=\frac{-12}{2}$$

Whakawehea te -12 ki te 2, kia riro ko -6.

$$z=-6$$

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

$$a=-6$$

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

$$b=-6$$

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

$$c=-6$$

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

$$d=-6$$

Kua oti te pūnaha te whakatau.

$$z=-6 a=-6 b=-6 c=-6 d=-6$$
