Whakaoti i te -2/3(x-3)-x=8

$$- \frac { 2 } { 3 } ( x - 3 ) - x = 8$$

Whakaoti mō x

$$x = -\frac{18}{5} = -3\frac{3}{5} = -3.6$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -\frac{2}{3} ki te x-3.

$$-\frac{2}{3}x-\frac{2}{3}\left(-3\right)-x=8$$

Tuhia te -\frac{2}{3}\left(-3\right) hei hautanga kotahi.

$$-\frac{2}{3}x+\frac{-2\left(-3\right)}{3}-x=8$$

Whakareatia te -2 ki te -3, ka 6.

$$-\frac{2}{3}x+\frac{6}{3}-x=8$$

Whakawehea te 6 ki te 3, kia riro ko 2.

$$-\frac{2}{3}x+2-x=8$$

Pahekotia te -\frac{2}{3}x me -x, ka -\frac{5}{3}x.

$$-\frac{5}{3}x+2=8$$

Tangohia te 2 mai i ngā taha e rua.

$$-\frac{5}{3}x=8-2$$

Tangohia te 2 i te 8, ka 6.

$$-\frac{5}{3}x=6$$

Me whakarea ngā taha e rua ki te -\frac{3}{5}, te tau utu o -\frac{5}{3}.

$$x=6\left(-\frac{3}{5}\right)$$

Tuhia te 6\left(-\frac{3}{5}\right) hei hautanga kotahi.

$$x=\frac{6\left(-3\right)}{5}$$

Whakareatia te 6 ki te -3, ka -18.

$$x=\frac{-18}{5}$$

Ka taea te hautanga \frac{-18}{5} te tuhi anō ko -\frac{18}{5} mā te tango i te tohu tōraro.

$$x=-\frac{18}{5}$$
