$$\frac{ 12 }{ 100 } 600+ \frac{ 300x }{ 100 } > \frac{ 15 }{ 100 } \left( 600+x \right)$$

Whakaoti mō x

$$x>\frac{120}{19}$$

Ngā Upane Otinga

Whakareatia ngā taha e rua o te whārite ki te 100. I te mea he tōrunga te 100, kāore e huri te ahunga koreōrite.

$$12\times 600+300x>15\left(600+x\right)$$

Whakareatia te 12 ki te 600, ka 7200.

$$7200+300x>15\left(600+x\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te 15 ki te 600+x.

$$7200+300x>9000+15x$$

Tangohia te 15x mai i ngā taha e rua.

$$7200+300x-15x>9000$$

Pahekotia te 300x me -15x, ka 285x.

$$7200+285x>9000$$

Tangohia te 7200 mai i ngā taha e rua.

$$285x>9000-7200$$

Tangohia te 7200 i te 9000, ka 1800.

$$285x>1800$$

Whakawehea ngā taha e rua ki te 285. I te mea he tōrunga te 285, kāore e huri te ahunga koreōrite.

$$x>\frac{1800}{285}$$

Whakahekea te hautanga \frac{1800}{285} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 15.

$$x>\frac{120}{19}$$
