Whakaoti i te -2/3left(1-xright)=1-x

$$- \frac{ 2 }{ 3 } \left( 1-x \right) = 1-x$$

Whakaoti mō x

$$x=1$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te -\frac{2}{3} ki te 1-x.

$$-\frac{2}{3}-\frac{2}{3}\left(-1\right)x=1-x$$

Whakareatia te -\frac{2}{3} ki te -1, ka \frac{2}{3}.

$$-\frac{2}{3}+\frac{2}{3}x=1-x$$

Me tāpiri te x ki ngā taha e rua.

$$-\frac{2}{3}+\frac{2}{3}x+x=1$$

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

$$-\frac{2}{3}+\frac{5}{3}x=1$$

Me tāpiri te \frac{2}{3} ki ngā taha e rua.

$$\frac{5}{3}x=1+\frac{2}{3}$$

Me tahuri te 1 ki te hautau \frac{3}{3}.

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

Tā te mea he rite te tauraro o \frac{3}{3} me \frac{2}{3}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

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

Tāpirihia te 3 ki te 2, ka 5.

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

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

$$x=\frac{5}{3}\times \frac{3}{5}$$

Me whakakore atu te \frac{5}{3} me tōna tau utu \frac{3}{5}.

$$x=1$$
