Issolvi 18(x+6.7)=(x+8.7)20

$$18(x+6.7)=(x+8.7)20$$

Solvi għal x

$$x=-26.7$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika 18 b'x+6.7.

$$18x+120.6=\left(x+8.7\right)\times 20$$

Uża l-propjetà distributtiva biex timmultiplika x+8.7 b'20.

$$18x+120.6=20x+174$$

Naqqas 20x miż-żewġ naħat.

$$18x+120.6-20x=174$$

Ikkombina 18x u -20x biex tikseb -2x.

$$-2x+120.6=174$$

Naqqas 120.6 miż-żewġ naħat.

$$-2x=174-120.6$$

Naqqas 120.6 minn 174 biex tikseb 53.4.

$$-2x=53.4$$

Iddividi ż-żewġ naħat b'-2.

$$x=\frac{53.4}{-2}$$

Espandi \frac{53.4}{-2} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'10.

$$x=\frac{534}{-20}$$

Naqqas il-frazzjoni \frac{534}{-20} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 2.

$$x=-\frac{267}{10}$$
