Whakaoti mō x

$$x\geq \frac{3}{50}$$

Ngā Upane Otinga

Whakawehea ngā taha e rua ki te 115. I te mea he tōrunga te 115, kāore e huri te ahunga koreōrite.

$$268-200\left(1-x\right)\geq \frac{9200}{115}$$

Whakawehea te 9200 ki te 115, kia riro ko 80.

$$268-200\left(1-x\right)\geq 80$$

Whakamahia te āhuatanga tohatoha hei whakarea te -200 ki te 1-x.

$$268-200+200x\geq 80$$

Tangohia te 200 i te 268, ka 68.

$$68+200x\geq 80$$

Tangohia te 68 mai i ngā taha e rua.

$$200x\geq 80-68$$

Tangohia te 68 i te 80, ka 12.

$$200x\geq 12$$

Whakawehea ngā taha e rua ki te 200. I te mea he tōrunga te 200, kāore e huri te ahunga koreōrite.

$$x\geq \frac{12}{200}$$

Whakahekea te hautanga \frac{12}{200} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 4.

$$x\geq \frac{3}{50}$$
