Ngā Upane Otinga

Whakareatia te 1 ki te 4, ka 4.

$$-5\left(2.4v-4\right)\geq -6\left(0.8+1.2v\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -5 ki te 2.4v-4.

$$-12v+20\geq -6\left(0.8+1.2v\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te -6 ki te 0.8+1.2v.

$$-12v+20\geq -4.8-7.2v$$

Me tāpiri te 7.2v ki ngā taha e rua.

$$-12v+20+7.2v\geq -4.8$$

Pahekotia te -12v me 7.2v, ka -4.8v.

$$-4.8v+20\geq -4.8$$

Tangohia te 20 mai i ngā taha e rua.

$$-4.8v\geq -4.8-20$$

Tangohia te 20 i te -4.8, ka -24.8.

$$-4.8v\geq -24.8$$

Whakawehea ngā taha e rua ki te -4.8. I te mea he tōraro a -4.8, ka huri te ahunga koreōrite.

$$v\leq \frac{-24.8}{-4.8}$$

Whakarohaina te \frac{-24.8}{-4.8} mā te whakarea i te taurunga me te tauraro ki te 10.

$$v\leq \frac{-248}{-48}$$

Whakahekea te hautanga \frac{-248}{-48} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -8.

$$v\leq \frac{31}{6}$$
