Issolvi -3.6z+1.3=0.2(z-3)

$$-3.6z+1.3=0.2(z-3)$$

Solvi għal z

$$z=0.5$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika 0.2 b'z-3.

$$-3.6z+1.3=0.2z-0.6$$

Naqqas 0.2z miż-żewġ naħat.

$$-3.6z+1.3-0.2z=-0.6$$

Ikkombina -3.6z u -0.2z biex tikseb -3.8z.

$$-3.8z+1.3=-0.6$$

Naqqas 1.3 miż-żewġ naħat.

$$-3.8z=-0.6-1.3$$

Naqqas 1.3 minn -0.6 biex tikseb -1.9.

$$-3.8z=-1.9$$

Iddividi ż-żewġ naħat b'-3.8.

$$z=\frac{-1.9}{-3.8}$$

Espandi \frac{-1.9}{-3.8} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'10.

$$z=\frac{-19}{-38}$$

Naqqas il-frazzjoni \frac{-19}{-38} għat-termini l-aktar baxxi billi testratta u tikkanċella barra -19.

$$z=\frac{1}{2}$$
