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

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

Whakaoti mō x

$$x = \frac{15}{7} = 2\frac{1}{7} \approx 2.142857143$$

Ngā Upane mō te Whakaoti Whārite Rārangi

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

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

Me whakakore te 3 me te 3.

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

Pahekotia te 2x me -\frac{2}{3}x, ka \frac{4}{3}x.

$$\frac{4}{3}x-2=-x+3$$

Me tāpiri te x ki ngā taha e rua.

$$\frac{4}{3}x-2+x=3$$

Pahekotia te \frac{4}{3}x me x, ka \frac{7}{3}x.

$$\frac{7}{3}x-2=3$$

Me tāpiri te 2 ki ngā taha e rua.

$$\frac{7}{3}x=3+2$$

Tāpirihia te 3 ki te 2, ka 5.

$$\frac{7}{3}x=5$$

Me whakarea ngā taha e rua ki te \frac{3}{7}, te tau utu o \frac{7}{3}.

$$x=5\times \frac{3}{7}$$

Tuhia te 5\times \frac{3}{7} hei hautanga kotahi.

$$x=\frac{5\times 3}{7}$$

Whakareatia te 5 ki te 3, ka 15.

$$x=\frac{15}{7}$$
