Kua tāruatia ki te papatopenga
-10\times 45x\geq 9\left(3\times 10+5\right)
Me whakarea ngā taha e rua o te whārite ki te 90, arā, te tauraro pātahi he tino iti rawa te kitea o -9,10. I te mea he tōrunga te 90, kāore e huri te ahunga koreōrite.
-450x\geq 9\left(3\times 10+5\right)
Whakareatia te -10 ki te 45, ka -450.
-450x\geq 9\left(30+5\right)
Whakareatia te 3 ki te 10, ka 30.
-450x\geq 9\times 35
Tāpirihia te 30 ki te 5, ka 35.
-450x\geq 315
Whakareatia te 9 ki te 35, ka 315.
x\leq \frac{315}{-450}
Whakawehea ngā taha e rua ki te -450. I te mea he tōraro a -450, ka huri te ahunga koreōrite.
x\leq -\frac{7}{10}
Whakahekea te hautanga \frac{315}{-450} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 45.
