Whakaoti i te 45-16*15-15(1+02)mgeq3

$$45 - 16 \times 15 - 15 ( 1 + 02 ) m \geq 3$$

Whakaoti mō m

$$m\leq -\frac{66}{5}$$

Ngā Upane Otinga

Whakareatia te 16 ki te 15, ka 240.

$$45-240-15\left(1+0\times 2\right)m\geq 3$$

Tangohia te 240 i te 45, ka -195.

$$-195-15\left(1+0\times 2\right)m\geq 3$$

Whakareatia te 0 ki te 2, ka 0.

$$-195-15\left(1+0\right)m\geq 3$$

Tāpirihia te 1 ki te 0, ka 1.

$$-195-15\times 1m\geq 3$$

Whakareatia te 15 ki te 1, ka 15.

$$-195-15m\geq 3$$

Me tāpiri te 195 ki ngā taha e rua.

$$-15m\geq 3+195$$

Tāpirihia te 3 ki te 195, ka 198.

$$-15m\geq 198$$

Whakawehea ngā taha e rua ki te -15. I te mea he tōraro a -15, ka huri te ahunga koreōrite.

$$m\leq \frac{198}{-15}$$

Whakahekea te hautanga \frac{198}{-15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.

$$m\leq -\frac{66}{5}$$
