Whakaoti i te 2-x=4-3/5+2(7-x)

$$2-x= \frac{ 4-3 }{ 5+2 } (7-x)$$

Whakaoti mō x

$$x = \frac{7}{6} = 1\frac{1}{6} \approx 1.166666667$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te 3 i te 4, ka 1.

$$2-x=\frac{1}{5+2}\left(7-x\right)$$

Tāpirihia te 5 ki te 2, ka 7.

$$2-x=\frac{1}{7}\left(7-x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te \frac{1}{7} ki te 7-x.

$$2-x=\frac{1}{7}\times 7+\frac{1}{7}\left(-1\right)x$$

Me whakakore te 7 me te 7.

$$2-x=1+\frac{1}{7}\left(-1\right)x$$

Whakareatia te \frac{1}{7} ki te -1, ka -\frac{1}{7}.

$$2-x=1-\frac{1}{7}x$$

Me tāpiri te \frac{1}{7}x ki ngā taha e rua.

$$2-x+\frac{1}{7}x=1$$

Pahekotia te -x me \frac{1}{7}x, ka -\frac{6}{7}x.

$$2-\frac{6}{7}x=1$$

Tangohia te 2 mai i ngā taha e rua.

$$-\frac{6}{7}x=1-2$$

Tangohia te 2 i te 1, ka -1.

$$-\frac{6}{7}x=-1$$

Me whakarea ngā taha e rua ki te -\frac{7}{6}, te tau utu o -\frac{6}{7}.

$$x=-\left(-\frac{7}{6}\right)$$

Whakareatia te -1 ki te -\frac{7}{6}, ka \frac{7}{6}.

$$x=\frac{7}{6}$$
