$$\left( 100-x \right) 2205 = \left( x-10 \right) 336+ \left( x-10 \right) 4200 \times 001$$

Whakaoti mō x

$$x = \frac{10660}{121} = 88\frac{12}{121} \approx 88.099173554$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakamahia te āhuatanga tohatoha hei whakarea te 100-x ki te 2205.

$$220500-2205x=\left(x-10\right)\times 336+\left(x-10\right)\times 4200\times 0\times 0\times 1$$

Whakamahia te āhuatanga tohatoha hei whakarea te x-10 ki te 336.

$$220500-2205x=336x-3360+\left(x-10\right)\times 4200\times 0\times 0\times 1$$

Whakareatia te 4200 ki te 0, ka 0.

$$220500-2205x=336x-3360+\left(x-10\right)\times 0\times 0\times 1$$

Whakareatia te 0 ki te 0, ka 0.

$$220500-2205x=336x-3360+\left(x-10\right)\times 0\times 1$$

Whakareatia te 0 ki te 1, ka 0.

$$220500-2205x=336x-3360+\left(x-10\right)\times 0$$

Ko te tau i whakarea ki te kore ka hua ko te kore.

$$220500-2205x=336x-3360+0$$

Tāpirihia te -3360 ki te 0, ka -3360.

$$220500-2205x=336x-3360$$

Tangohia te 336x mai i ngā taha e rua.

$$220500-2205x-336x=-3360$$

Pahekotia te -2205x me -336x, ka -2541x.

$$220500-2541x=-3360$$

Tangohia te 220500 mai i ngā taha e rua.

$$-2541x=-3360-220500$$

Tangohia te 220500 i te -3360, ka -223860.

$$-2541x=-223860$$

Whakawehea ngā taha e rua ki te -2541.

$$x=\frac{-223860}{-2541}$$

Whakahekea te hautanga \frac{-223860}{-2541} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -21.

$$x=\frac{10660}{121}$$
