Whakaoti i te 2x-5/7geq-1

$$2 x - \frac { 5 } { 7 } \geq - 1$$

Whakaoti mō x

$$x\geq -\frac{1}{7}$$

Ngā Upane Otinga

Me tāpiri te \frac{5}{7} ki ngā taha e rua.

$$2x\geq -1+\frac{5}{7}$$

Me tahuri te -1 ki te hautau -\frac{7}{7}.

$$2x\geq -\frac{7}{7}+\frac{5}{7}$$

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

$$2x\geq \frac{-7+5}{7}$$

Tāpirihia te -7 ki te 5, ka -2.

$$2x\geq -\frac{2}{7}$$

Whakawehea ngā taha e rua ki te 2. I te mea he tōrunga te 2, kāore e huri te ahunga koreōrite.

$$x\geq \frac{-\frac{2}{7}}{2}$$

Tuhia te \frac{-\frac{2}{7}}{2} hei hautanga kotahi.

$$x\geq \frac{-2}{7\times 2}$$

Whakareatia te 7 ki te 2, ka 14.

$$x\geq \frac{-2}{14}$$

Whakahekea te hautanga \frac{-2}{14} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.

$$x\geq -\frac{1}{7}$$
