Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika 2 b'400-600x.

$$800-1200x-6.5\times 2=2-200x-15$$

Immultiplika 6.5 u 2 biex tikseb 13.

$$800-1200x-13=2-200x-15$$

Naqqas 13 minn 800 biex tikseb 787.

$$787-1200x=2-200x-15$$

Naqqas 15 minn 2 biex tikseb -13.

$$787-1200x=-13-200x$$

Żid 200x maż-żewġ naħat.

$$787-1200x+200x=-13$$

Ikkombina -1200x u 200x biex tikseb -1000x.

$$787-1000x=-13$$

Naqqas 787 miż-żewġ naħat.

$$-1000x=-13-787$$

Naqqas 787 minn -13 biex tikseb -800.

$$-1000x=-800$$

Iddividi ż-żewġ naħat b'-1000.

$$x=\frac{-800}{-1000}$$

Naqqas il-frazzjoni \frac{-800}{-1000} għat-termini l-aktar baxxi billi testratta u tikkanċella barra -200.

$$x=\frac{4}{5}$$
