Passi tas-Soluzzjonijiet

Uża l-propjetà distributtiva biex timmultiplika -2 b'x-5.

$$-3x-7-2x+10\leq 2\left(x-5.5\right)$$

Ikkombina -3x u -2x biex tikseb -5x.

$$-5x-7+10\leq 2\left(x-5.5\right)$$

Żid -7 u 10 biex tikseb 3.

$$-5x+3\leq 2\left(x-5.5\right)$$

Uża l-propjetà distributtiva biex timmultiplika 2 b'x-5.5.

$$-5x+3\leq 2x-11$$

Naqqas 2x miż-żewġ naħat.

$$-5x+3-2x\leq -11$$

Ikkombina -5x u -2x biex tikseb -7x.

$$-7x+3\leq -11$$

Naqqas 3 miż-żewġ naħat.

$$-7x\leq -11-3$$

Naqqas 3 minn -11 biex tikseb -14.

$$-7x\leq -14$$

Iddividi ż-żewġ naħat b'-7. Peress li -7 huwa negattiv, id-direzzjoni tal-inugwaljanza inbidlet.

$$x\geq \frac{-14}{-7}$$

Iddividi -14 b'-7 biex tikseb2.

$$x\geq 2$$
