Whakaoti i te 3(x-1)geq1

$$3 ( x - 1 ) \geq 1$$

Whakaoti mō x

$$x\geq \frac{4}{3}$$

Ngā Upane Otinga

Whakawehea ngā taha e rua ki te 3. I te mea he tōrunga te 3, kāore e huri te ahunga koreōrite.

$$x-1\geq \frac{1}{3}$$

Me tāpiri te 1 ki ngā taha e rua.

$$x\geq \frac{1}{3}+1$$

Me tahuri te 1 ki te hautau \frac{3}{3}.

$$x\geq \frac{1}{3}+\frac{3}{3}$$

Tā te mea he rite te tauraro o \frac{1}{3} me \frac{3}{3}, me tāpiri rāua mā te tāpiri i ō raua taurunga.

$$x\geq \frac{1+3}{3}$$

Tāpirihia te 1 ki te 3, ka 4.

$$x\geq \frac{4}{3}$$
