Whakaoti i te {l}{5y=55}{26-7y=x}{z=x-6}{a=z}{b=a}{text{Solvefor}ctext{where}}{c=b}

$$\left. \begin{array} { l } { 5 y = 55 }\\ { 26 - 7 y = x }\\ { z = x - 6 }\\ { a = z }\\ { b = a }\\ { \text{Solve for } c \text{ where} } \\ { c = b } \end{array} \right.$$

Whakaoti mō y, x, z, a, b, c

$$c=-57$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakawehea ngā taha e rua ki te 5.

$$y=\frac{55}{5}$$

Whakawehea te 55 ki te 5, kia riro ko 11.

$$y=11$$

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

$$26-7\times 11=x$$

Whakareatia te -7 ki te 11, ka -77.

$$26-77=x$$

Tangohia te 77 i te 26, ka -51.

$$-51=x$$

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

$$x=-51$$

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

$$z=-51-6$$

Tangohia te 6 i te -51, ka -57.

$$z=-57$$

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

$$a=-57$$

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

$$b=-57$$

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

$$c=-57$$

Kua oti te pūnaha te whakatau.

$$y=11 x=-51 z=-57 a=-57 b=-57 c=-57$$
