Whakaoti i te x=23/8*(3-x)

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

Whakaoti mō x

$$x = \frac{19}{9} = 2\frac{1}{9} \approx 2.111111111$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 2 ki te 8, ka 16.

$$x=\frac{16+3}{8}\left(3-x\right)$$

Tāpirihia te 16 ki te 3, ka 19.

$$x=\frac{19}{8}\left(3-x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te \frac{19}{8} ki te 3-x.

$$x=\frac{19}{8}\times 3+\frac{19}{8}\left(-1\right)x$$

Tuhia te \frac{19}{8}\times 3 hei hautanga kotahi.

$$x=\frac{19\times 3}{8}+\frac{19}{8}\left(-1\right)x$$

Whakareatia te 19 ki te 3, ka 57.

$$x=\frac{57}{8}+\frac{19}{8}\left(-1\right)x$$

Whakareatia te \frac{19}{8} ki te -1, ka -\frac{19}{8}.

$$x=\frac{57}{8}-\frac{19}{8}x$$

Me tāpiri te \frac{19}{8}x ki ngā taha e rua.

$$x+\frac{19}{8}x=\frac{57}{8}$$

Pahekotia te x me \frac{19}{8}x, ka \frac{27}{8}x.

$$\frac{27}{8}x=\frac{57}{8}$$

Me whakarea ngā taha e rua ki te \frac{8}{27}, te tau utu o \frac{27}{8}.

$$x=\frac{57}{8}\times \frac{8}{27}$$

Me whakarea te \frac{57}{8} ki te \frac{8}{27} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x=\frac{57\times 8}{8\times 27}$$

Me whakakore tahi te 8 i te taurunga me te tauraro.

$$x=\frac{57}{27}$$

Whakahekea te hautanga \frac{57}{27} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$x=\frac{19}{9}$$
