Whakaoti i te {l}{45x+4.5x=44x+7.70}{y=0*0*0}{z=y}{a=z}{text{Solvefor}btext{where}}{b=a}

$$\left. \begin{array} { l } { 45 x + 4.5 x = 44 x + 7.70 }\\ { y = 0 \cdot 0 \cdot 0 }\\ { z = y }\\ { a = z }\\ { \text{Solve for } b \text{ where} } \\ { b = a } \end{array} \right.$$

Whakaoti mō x, y, z, a, b

$$b=0$$

Ngā Upane Otinga

Whakaarohia te whārite tuatahi. Pahekotia te 45x me 4.5x, ka 49.5x.

$$49.5x=44x+7.7$$

Tangohia te 44x mai i ngā taha e rua.

$$49.5x-44x=7.7$$

Pahekotia te 49.5x me -44x, ka 5.5x.

$$5.5x=7.7$$

Whakawehea ngā taha e rua ki te 5.5.

$$x=\frac{7.7}{5.5}$$

Whakarohaina te \frac{7.7}{5.5} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{77}{55}$$

Whakahekea te hautanga \frac{77}{55} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 11.

$$x=\frac{7}{5}$$

Whakaarohia te whārite tuarua. Whakareatia te 0 ki te 0, ka 0.

$$y=0\times 0$$

Whakareatia te 0 ki te 0, ka 0.

$$y=0$$

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

$$z=0$$

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

$$a=0$$

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

$$b=0$$

Kua oti te pūnaha te whakatau.

$$x=\frac{7}{5} y=0 z=0 a=0 b=0$$
