Whakaoti i te {l}{7x-2y=35}{x=-9}{z=y}{a=z}{b=a}{text{Solvefor}ctext{where}}{c=b}

$$\left. \begin{array} { l } { 7 x - 2 y = 35 }\\ { x = -9 }\\ { z = y }\\ { a = z }\\ { b = a }\\ { \text{Solve for } c \text{ where} } \\ { c = b } \end{array} \right.$$

Whakaoti mō x, y, z, a, b, c

$$c=-49$$

Ngā Upane Otinga

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

$$7\left(-9\right)-2y=35$$

Whakareatia te 7 ki te -9, ka -63.

$$-63-2y=35$$

Me tāpiri te 63 ki ngā taha e rua.

$$-2y=35+63$$

Tāpirihia te 35 ki te 63, ka 98.

$$-2y=98$$

Whakawehea ngā taha e rua ki te -2.

$$y=\frac{98}{-2}$$

Whakawehea te 98 ki te -2, kia riro ko -49.

$$y=-49$$

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

$$z=-49$$

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

$$a=-49$$

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

$$b=-49$$

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

$$c=-49$$

Kua oti te pūnaha te whakatau.

$$x=-9 y=-49 z=-49 a=-49 b=-49 c=-49$$
