Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3. I te mea he tōrunga te 6, kāore e huri te ahunga koreōrite.

$$3\left(13+1\right)\geq 54\times \frac{4}{3}-30$$

Tāpirihia te 13 ki te 1, ka 14.

$$3\times 14\geq 54\times \frac{4}{3}-30$$

Whakareatia te 3 ki te 14, ka 42.

$$42\geq 54\times \frac{4}{3}-30$$

Tuhia te 54\times \frac{4}{3} hei hautanga kotahi.

$$42\geq \frac{54\times 4}{3}-30$$

Whakareatia te 54 ki te 4, ka 216.

$$42\geq \frac{216}{3}-30$$

Whakawehea te 216 ki te 3, kia riro ko 72.

$$42\geq 72-30$$

Tangohia te 30 i te 72, ka 42.

$$42\geq 42$$

Whakatauritea te 42 me te 42.
