Issolvi 0.4(7x+14)=1.6-(x+2)

$$0.4 ( 7 x + 14 ) = 1.6 - ( x + 2 )$$

Solvi għal x

$$x = -\frac{30}{19} = -1\frac{11}{19} \approx -1.578947368$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika 0.4 b'7x+14.

$$2.8x+5.6=1.6-\left(x+2\right)$$

Biex issib l-oppost ta' x+2, sib l-oppost ta' kull terminu.

$$2.8x+5.6=1.6-x-2$$

Naqqas 2 minn 1.6 biex tikseb -0.4.

$$2.8x+5.6=-0.4-x$$

Żid x maż-żewġ naħat.

$$2.8x+5.6+x=-0.4$$

Ikkombina 2.8x u x biex tikseb 3.8x.

$$3.8x+5.6=-0.4$$

Naqqas 5.6 miż-żewġ naħat.

$$3.8x=-0.4-5.6$$

Naqqas 5.6 minn -0.4 biex tikseb -6.

$$3.8x=-6$$

Iddividi ż-żewġ naħat b'3.8.

$$x=\frac{-6}{3.8}$$

Espandi \frac{-6}{3.8} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'10.

$$x=\frac{-60}{38}$$

Naqqas il-frazzjoni \frac{-60}{38} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 2.

$$x=-\frac{30}{19}$$
