Whakaoti i te 7(3-x)geq5

$$7 ( 3 - x ) \geq 5$$

Whakaoti mō x

$$x\leq \frac{16}{7}$$

Ngā Upane Otinga

Whakawehea ngā taha e rua ki te 7. Nō te mea he >0 te 7, ka noho pērā tonu te ahunga koreōrite.

$$3-x\geq \frac{5}{7}$$

Tangohia te 3 mai i ngā taha e rua.

$$-x\geq \frac{5}{7}-3$$

Me tahuri te 3 ki te hautau \frac{21}{7}.

$$-x\geq \frac{5}{7}-\frac{21}{7}$$

Tā te mea he rite te tauraro o \frac{5}{7} me \frac{21}{7}, me tango rāua mā te tango i ō raua taurunga.

$$-x\geq \frac{5-21}{7}$$

Tangohia te 21 i te 5, ka -16.

$$-x\geq -\frac{16}{7}$$

Whakawehea ngā taha e rua ki te -1. Nō te mea he <0 te -1, ka hurihia te ahunga koreōrite.

$$x\leq \frac{-\frac{16}{7}}{-1}$$

Tuhia te \frac{-\frac{16}{7}}{-1} hei hautanga kotahi.

$$x\leq \frac{-16}{7\left(-1\right)}$$

Whakareatia te 7 ki te -1, ka -7.

$$x\leq \frac{-16}{-7}$$

Ka taea te hautanga \frac{-16}{-7} te whakamāmā ki te \frac{16}{7} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.

$$x\leq \frac{16}{7}$$
