Whakaoti i te 2x-6+3xgeq8x+21

$$2x-6+3x \geq 8x+21$$

Whakaoti mō x

$$x\leq -9$$

Ngā Upane Otinga

Pahekotia te 2x me 3x, ka 5x.

$$5x-6\geq 8x+21$$

Tangohia te 8x mai i ngā taha e rua.

$$5x-6-8x\geq 21$$

Pahekotia te 5x me -8x, ka -3x.

$$-3x-6\geq 21$$

Me tāpiri te 6 ki ngā taha e rua.

$$-3x\geq 21+6$$

Tāpirihia te 21 ki te 6, ka 27.

$$-3x\geq 27$$

Whakawehea ngā taha e rua ki te -3. I te mea he tōraro a -3, ka huri te ahunga koreōrite.

$$x\leq \frac{27}{-3}$$

Whakawehea te 27 ki te -3, kia riro ko -9.

$$x\leq -9$$
