Issolvi 9x+1.2=(-x+0.8/2+0.8)*10

$$9 x + 1.2 = ( - \frac { x + 0.8 } { 2 } + 0.8 ) \cdot 10$$

Solvi għal x

$$x=0.2$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika ż-żewġ naħat tal-ekwazzjoni b'2.

$$18x+2.4=2\left(-\frac{x+0.8}{2}+0.8\right)\times 10$$

Immultiplika 2 u 10 biex tikseb 20.

$$18x+2.4=20\left(-\frac{x+0.8}{2}+0.8\right)$$

Uża l-propjetà distributtiva biex timmultiplika 20 b'-\frac{x+0.8}{2}+0.8.

$$18x+2.4=20\left(-\frac{x+0.8}{2}\right)+16$$

Iddividi kull terminu ta' x+0.8 b'2 biex tikseb\frac{1}{2}x+0.4.

$$18x+2.4=20\left(-\left(\frac{1}{2}x+0.4\right)\right)+16$$

Biex issib l-oppost ta' \frac{1}{2}x+0.4, sib l-oppost ta' kull terminu.

$$18x+2.4=20\left(-\frac{1}{2}x-0.4\right)+16$$

Uża l-propjetà distributtiva biex timmultiplika 20 b'-\frac{1}{2}x-0.4.

$$18x+2.4=20\left(-\frac{1}{2}\right)x-8+16$$

Esprimi 20\left(-\frac{1}{2}\right) bħala frazzjoni waħda.

$$18x+2.4=\frac{20\left(-1\right)}{2}x-8+16$$

Immultiplika 20 u -1 biex tikseb -20.

$$18x+2.4=\frac{-20}{2}x-8+16$$

Iddividi -20 b'2 biex tikseb-10.

$$18x+2.4=-10x-8+16$$

Żid -8 u 16 biex tikseb 8.

$$18x+2.4=-10x+8$$

Żid 10x maż-żewġ naħat.

$$18x+2.4+10x=8$$

Ikkombina 18x u 10x biex tikseb 28x.

$$28x+2.4=8$$

Naqqas 2.4 miż-żewġ naħat.

$$28x=8-2.4$$

Naqqas 2.4 minn 8 biex tikseb 5.6.

$$28x=5.6$$

Iddividi ż-żewġ naħat b'28.

$$x=\frac{5.6}{28}$$

Espandi \frac{5.6}{28} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'10.

$$x=\frac{56}{280}$$

Naqqas il-frazzjoni \frac{56}{280} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 56.

$$x=\frac{1}{5}$$
