Whakaoti i te {l}{3x=18}{3y=9}{2z-z=6}{a=y*x-z}{b=a}{text{Solvefor}ctext{where}}{c=b}

$$\left. \begin{array} { l } { 3 x = 18 }\\ { 3 y = 9 }\\ { 2 z - z = 6 }\\ { a = y \cdot x - z }\\ { b = a }\\ { \text{Solve for } c \text{ where} } \\ { c = b } \end{array} \right.$$

Whakaoti mō x, y, z, a, b, c

$$c=12$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Whakawehea ngā taha e rua ki te 3.

$$x=\frac{18}{3}$$

Whakawehea te 18 ki te 3, kia riro ko 6.

$$x=6$$

Whakaarohia te whārite tuarua. Whakawehea ngā taha e rua ki te 3.

$$y=\frac{9}{3}$$

Whakawehea te 9 ki te 3, kia riro ko 3.

$$y=3$$

Whakaarohia te whārite tuatoru. Pahekotia te 2z me -z, ka z.

$$z=6$$

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

$$a=3\times 6-6$$

Mahia ngā whakarea.

$$a=18-6$$

Tangohia te 6 i te 18, ka 12.

$$a=12$$

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

$$b=12$$

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

$$c=12$$

Kua oti te pūnaha te whakatau.

$$x=6 y=3 z=6 a=12 b=12 c=12$$
