Whakaoti i te 1100%x+1500%(x+900)=213

$$1100 \% x + 1500 \% ( x + 900 ) = 213$$

Whakaoti mō x

$$x = -\frac{13287}{26} = -511\frac{1}{26} \approx -511.038461538$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawehea te 1100 ki te 100, kia riro ko 11.

$$11x+\frac{1500}{100}\left(x+900\right)=213$$

Whakawehea te 1500 ki te 100, kia riro ko 15.

$$11x+15\left(x+900\right)=213$$

Whakamahia te āhuatanga tohatoha hei whakarea te 15 ki te x+900.

$$11x+15x+13500=213$$

Pahekotia te 11x me 15x, ka 26x.

$$26x+13500=213$$

Tangohia te 13500 mai i ngā taha e rua.

$$26x=213-13500$$

Tangohia te 13500 i te 213, ka -13287.

$$26x=-13287$$

Whakawehea ngā taha e rua ki te 26.

$$x=\frac{-13287}{26}$$

Ka taea te hautanga \frac{-13287}{26} te tuhi anō ko -\frac{13287}{26} mā te tango i te tohu tōraro.

$$x=-\frac{13287}{26}$$
