Whakaoti i te {l}{-2x-8=0}{y=2+2x-1}{z=y}{a=z}{b=a}{text{Solvefor}ctext{where}}{c=b}

$$\left. \begin{array} { l } { -2 x - 8 = 0 }\\ { y = 2 + 2 x - 1 }\\ { z = y }\\ { a = z }\\ { b = a }\\ { \text{Solve for } c \text{ where} } \\ { c = b } \end{array} \right.$$

Whakaoti mō x, y, z, a, b, c

$$c=-7$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Me tāpiri te 8 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.

$$-2x=8$$

Whakawehea ngā taha e rua ki te -2.

$$x=\frac{8}{-2}$$

Whakawehea te 8 ki te -2, kia riro ko -4.

$$x=-4$$

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

$$y=2+2\left(-4\right)-1$$

Whakareatia te 2 ki te -4, ka -8.

$$y=2-8-1$$

Tangohia te 8 i te 2, ka -6.

$$y=-6-1$$

Tangohia te 1 i te -6, ka -7.

$$y=-7$$

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

$$z=-7$$

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

$$a=-7$$

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

$$b=-7$$

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

$$c=-7$$

Kua oti te pūnaha te whakatau.

$$x=-4 y=-7 z=-7 a=-7 b=-7 c=-7$$
