Issolvi 0.60(z-300)+0.05z=0.70z-205

$$0.60 ( z - 300 ) + 0.05 z = 0.70 z - 205$$

Solvi għal z

$$z=500$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika 0.6 b'z-300.

$$0.6z-180+0.05z=0.7z-205$$

Ikkombina 0.6z u 0.05z biex tikseb 0.65z.

$$0.65z-180=0.7z-205$$

Naqqas 0.7z miż-żewġ naħat.

$$0.65z-180-0.7z=-205$$

Ikkombina 0.65z u -0.7z biex tikseb -0.05z.

$$-0.05z-180=-205$$

Żid 180 maż-żewġ naħat.

$$-0.05z=-205+180$$

Żid -205 u 180 biex tikseb -25.

$$-0.05z=-25$$

Iddividi ż-żewġ naħat b'-0.05.

$$z=\frac{-25}{-0.05}$$

Espandi \frac{-25}{-0.05} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'100.

$$z=\frac{-2500}{-5}$$

Iddividi -2500 b'-5 biex tikseb500.

$$z=500$$
