Whakaoti i te (100-T)*2205=(T-10)*336+(1-10)*1200*0

$$( 100 - T ) \times 2205 = ( T - 10 ) \times 336 + ( 1 - 10 ) \times 1200 \times 0$$

Whakaoti mō T

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

Ngā Upane mō te Whakaoti Whārite Rārangi

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

$$220500-2205T=\left(T-10\right)\times 336+\left(1-10\right)\times 1200\times 0$$

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

$$220500-2205T=336T-3360+\left(1-10\right)\times 1200\times 0$$

Tangohia te 10 i te 1, ka -9.

$$220500-2205T=336T-3360-9\times 1200\times 0$$

Whakareatia te -9 ki te 1200, ka -10800.

$$220500-2205T=336T-3360-10800\times 0$$

Whakareatia te -10800 ki te 0, ka 0.

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

Tāpirihia te -3360 ki te 0, ka -3360.

$$220500-2205T=336T-3360$$

Tangohia te 336T mai i ngā taha e rua.

$$220500-2205T-336T=-3360$$

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

$$220500-2541T=-3360$$

Tangohia te 220500 mai i ngā taha e rua.

$$-2541T=-3360-220500$$

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

$$-2541T=-223860$$

Whakawehea ngā taha e rua ki te -2541.

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

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

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