Whakaoti i te {l}{x=3}{y=2}{z=-7y^2}{a=z}{b=a}{text{Solvefor}ctext{where}}{c=b}

$$\left. \begin{array} { l } { x = 3 }\\ { y = 2 }\\ { z = -7 y ^ {2} }\\ { a = z }\\ { b = a }\\ { \text{Solve for } c \text{ where} } \\ { c = b } \end{array} \right.$$

Whakaoti mō x, y, z, a, b, c

$$c=-28$$

Ngā Upane Otinga

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

$$z=-7\times 2^{2}$$

Tātaihia te 2 mā te pū o 2, kia riro ko 4.

$$z=-7\times 4$$

Whakareatia te -7 ki te 4, ka -28.

$$z=-28$$

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

$$a=-28$$

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

$$b=-28$$

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

$$c=-28$$

Kua oti te pūnaha te whakatau.

$$x=3 y=2 z=-28 a=-28 b=-28 c=-28$$
