$$\left. \begin{array} { l } { -1 \cdot 5 {(3 + 22 t)} = 12 }\\ { u = t }\\ { v = u }\\ { \text{Solve for } w \text{ where} } \\ { w = v } \end{array} \right.$$

Whakaoti mō t, u, v, w

$$w=-\frac{27}{110}\approx -0.245454545$$

Whakaarohia te whārite tuatahi. Whakareatia te -1 ki te 5, ka -5.

$$-5\left(3+22t\right)=12$$

Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te 3+22t.

$$-15-110t=12$$

Me tāpiri te 15 ki ngā taha e rua.

$$-110t=12+15$$

Tāpirihia te 12 ki te 15, ka 27.

$$-110t=27$$

Whakawehea ngā taha e rua ki te -110.

$$t=-\frac{27}{110}$$

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

$$u=-\frac{27}{110}$$

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

$$v=-\frac{27}{110}$$

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

$$w=-\frac{27}{110}$$

Kua oti te pūnaha te whakatau.

$$t=-\frac{27}{110} u=-\frac{27}{110} v=-\frac{27}{110} w=-\frac{27}{110}$$
