Whakaoti i te {l}{-3u+1=4}{v=4u-5}{w=v}{x=w}{text{Solvefor}ytext{where}}{y=x}

$$\left. \begin{array} { l } { -3 u + 1 = 4 }\\ { v = 4 u - 5 }\\ { w = v }\\ { x = w }\\ { \text{Solve for } y \text{ where} } \\ { y = x } \end{array} \right.$$

Whakaoti mō u, v, w, x, y

$$y=-9$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Tangohia te 1 mai i ngā taha e rua.

$$-3u=4-1$$

Tangohia te 1 i te 4, ka 3.

$$-3u=3$$

Whakawehea ngā taha e rua ki te -3.

$$u=\frac{3}{-3}$$

Whakawehea te 3 ki te -3, kia riro ko -1.

$$u=-1$$

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

$$v=4\left(-1\right)-5$$

Whakareatia te 4 ki te -1, ka -4.

$$v=-4-5$$

Tangohia te 5 i te -4, ka -9.

$$v=-9$$

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

$$w=-9$$

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

$$x=-9$$

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

$$y=-9$$

Kua oti te pūnaha te whakatau.

$$u=-1 v=-9 w=-9 x=-9 y=-9$$
