Whakaoti i te 0.3(6x-x)=0.4(x+8)

$$0.3 ( 6 x - x ) = 0.4 ( x + 8 )$$

Whakaoti mō x

$$x = \frac{32}{11} = 2\frac{10}{11} \approx 2.909090909$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Pahekotia te 6x me -x, ka 5x.

$$0.3\times 5x=0.4\left(x+8\right)$$

Whakareatia te 0.3 ki te 5, ka 1.5.

$$1.5x=0.4\left(x+8\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 0.4 ki te x+8.

$$1.5x=0.4x+3.2$$

Tangohia te 0.4x mai i ngā taha e rua.

$$1.5x-0.4x=3.2$$

Pahekotia te 1.5x me -0.4x, ka 1.1x.

$$1.1x=3.2$$

Whakawehea ngā taha e rua ki te 1.1.

$$x=\frac{3.2}{1.1}$$

Whakarohaina te \frac{3.2}{1.1} mā te whakarea i te taurunga me te tauraro ki te 10.

$$x=\frac{32}{11}$$
