$$\left. \begin{array} { l } { -8 r - 3 = -5 r + 9 }\\ { s = r }\\ { t = s }\\ { u = t }\\ { v = u }\\ { w = v }\\ { \text{Solve for } x \text{ where} } \\ { x = w } \end{array} \right.$$

Whakaoti mō r, s, t, u, v, w, x

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Me tāpiri te 5r ki ngā taha e rua.

$$-8r-3+5r=9$$

Pahekotia te -8r me 5r, ka -3r.

$$-3r-3=9$$

Me tāpiri te 3 ki ngā taha e rua.

$$-3r=9+3$$

Tāpirihia te 9 ki te 3, ka 12.

$$-3r=12$$

Whakawehea ngā taha e rua ki te -3.

$$r=\frac{12}{-3}$$

Whakawehea te 12 ki te -3, kia riro ko -4.

$$r=-4$$

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

$$s=-4$$

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

$$t=-4$$

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

$$u=-4$$

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

$$v=-4$$

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

$$w=-4$$

Whakaarohia te whārite (7). Me kōkuhu ngā uara tāupe mōhiotia ki te whārite.

$$x=-4$$

Kua oti te pūnaha te whakatau.

$$r=-4 s=-4 t=-4 u=-4 v=-4 w=-4 x=-4$$
