Whakaoti i te -2a-1geq-1/2a-3

$$- 2 a - 1 \geq - \frac { 1 } { 2 } a - 3$$

Whakaoti mō a

$$a\leq \frac{4}{3}$$

Ngā Upane Otinga

Me tāpiri te \frac{1}{2}a ki ngā taha e rua.

$$-2a-1+\frac{1}{2}a\geq -3$$

Pahekotia te -2a me \frac{1}{2}a, ka -\frac{3}{2}a.

$$-\frac{3}{2}a-1\geq -3$$

Me tāpiri te 1 ki ngā taha e rua.

$$-\frac{3}{2}a\geq -3+1$$

Tāpirihia te -3 ki te 1, ka -2.

$$-\frac{3}{2}a\geq -2$$

Me whakarea ngā taha e rua ki te -\frac{2}{3}, te tau utu o -\frac{3}{2}. I te mea he tōraro a -\frac{3}{2}, ka huri te ahunga koreōrite.

$$a\leq -2\left(-\frac{2}{3}\right)$$

Tuhia te -2\left(-\frac{2}{3}\right) hei hautanga kotahi.

$$a\leq \frac{-2\left(-2\right)}{3}$$

Whakareatia te -2 ki te -2, ka 4.

$$a\leq \frac{4}{3}$$
