Whakaoti i te 11x-(x+1)*0.85=17

$$11 x - ( x + 1 ) \times 0.85 = 17$$

Whakaoti mō x

$$x = \frac{51}{29} = 1\frac{22}{29} \approx 1.75862069$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te x+1 ki te 0.85.

$$11x-\left(0.85x+0.85\right)=17$$

Hei kimi i te tauaro o 0.85x+0.85, kimihia te tauaro o ia taurangi.

$$11x-0.85x-0.85=17$$

Pahekotia te 11x me -0.85x, ka 10.15x.

$$10.15x-0.85=17$$

Me tāpiri te 0.85 ki ngā taha e rua.

$$10.15x=17+0.85$$

Tāpirihia te 17 ki te 0.85, ka 17.85.

$$10.15x=17.85$$

Whakawehea ngā taha e rua ki te 10.15.

$$x=\frac{17.85}{10.15}$$

Whakarohaina te \frac{17.85}{10.15} mā te whakarea i te taurunga me te tauraro ki te 100.

$$x=\frac{1785}{1015}$$

Whakahekea te hautanga \frac{1785}{1015} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 35.

$$x=\frac{51}{29}$$
