Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika 2.6 b'0.4x-1.4.

$$1.04x-3.64=-3.9\left(1.2x-0.9\right)$$

Uża l-propjetà distributtiva biex timmultiplika -3.9 b'1.2x-0.9.

$$1.04x-3.64=-4.68x+3.51$$

Żid 4.68x maż-żewġ naħat.

$$1.04x-3.64+4.68x=3.51$$

Ikkombina 1.04x u 4.68x biex tikseb 5.72x.

$$5.72x-3.64=3.51$$

Żid 3.64 maż-żewġ naħat.

$$5.72x=3.51+3.64$$

Żid 3.51 u 3.64 biex tikseb 7.15.

$$5.72x=7.15$$

Iddividi ż-żewġ naħat b'5.72.

$$x=\frac{7.15}{5.72}$$

Espandi \frac{7.15}{5.72} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'100.

$$x=\frac{715}{572}$$

Naqqas il-frazzjoni \frac{715}{572} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 143.

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