Whakaoti i te x=11/8-3/8x+2

$$x = 1 \frac { 1 } { 8 } - \frac { 3 } { 8 } x + 2$$

Whakaoti mō x

$$x = \frac{25}{11} = 2\frac{3}{11} \approx 2.272727273$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia te 1 ki te 8, ka 8.

$$x=\frac{8+1}{8}-\frac{3}{8}x+2$$

Tāpirihia te 8 ki te 1, ka 9.

$$x=\frac{9}{8}-\frac{3}{8}x+2$$

Me tahuri te 2 ki te hautau \frac{16}{8}.

$$x=\frac{9}{8}-\frac{3}{8}x+\frac{16}{8}$$

Tā te mea he rite te tauraro o \frac{9}{8} me \frac{16}{8}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$x=\frac{9+16}{8}-\frac{3}{8}x$$

Tāpirihia te 9 ki te 16, ka 25.

$$x=\frac{25}{8}-\frac{3}{8}x$$

Me tāpiri te \frac{3}{8}x ki ngā taha e rua.

$$x+\frac{3}{8}x=\frac{25}{8}$$

Pahekotia te x me \frac{3}{8}x, ka \frac{11}{8}x.

$$\frac{11}{8}x=\frac{25}{8}$$

Me whakarea ngā taha e rua ki te \frac{8}{11}, te tau utu o \frac{11}{8}.

$$x=\frac{25}{8}\times \frac{8}{11}$$

Me whakarea te \frac{25}{8} ki te \frac{8}{11} mā te whakarea taurunga ki te taurunga me te tauraro ki te tauraro.

$$x=\frac{25\times 8}{8\times 11}$$

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

$$x=\frac{25}{11}$$
