Issolvi 3*0.4+2*5.4y=1

$$3 \times 0.4+2 \times 5.4y=1$$

Solvi għal y

$$y=-\frac{1}{54}\approx -0.018518519$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika 3 u 0.4 biex tikseb 1.2.

$$1.2+2\times 5.4y=1$$

Immultiplika 2 u 5.4 biex tikseb 10.8.

$$1.2+10.8y=1$$

Naqqas 1.2 miż-żewġ naħat.

$$10.8y=1-1.2$$

Naqqas 1.2 minn 1 biex tikseb -0.2.

$$10.8y=-0.2$$

Iddividi ż-żewġ naħat b'10.8.

$$y=\frac{-0.2}{10.8}$$

Espandi \frac{-0.2}{10.8} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'10.

$$y=\frac{-2}{108}$$

Naqqas il-frazzjoni \frac{-2}{108} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 2.

$$y=-\frac{1}{54}$$
