Issolvi (x-500)*0.75+500*0.1=(1-0.15)x

$$( x - 500 ) \times 0.75 + 500 \times 0.1 = ( 1 - 0.15 ) x$$

Solvi għal x

$$x=-3250$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika x-500 b'0.75.

$$0.75x-375+500\times 0.1=\left(1-0.15\right)x$$

Immultiplika 500 u 0.1 biex tikseb 50.

$$0.75x-375+50=\left(1-0.15\right)x$$

Żid -375 u 50 biex tikseb -325.

$$0.75x-325=\left(1-0.15\right)x$$

Naqqas 0.15 minn 1 biex tikseb 0.85.

$$0.75x-325=0.85x$$

Naqqas 0.85x miż-żewġ naħat.

$$0.75x-325-0.85x=0$$

Ikkombina 0.75x u -0.85x biex tikseb -0.1x.

$$-0.1x-325=0$$

Żid 325 maż-żewġ naħat. Xi ħaġa plus żero jirriżulta f'dan in-numru stess.

$$-0.1x=325$$

Iddividi ż-żewġ naħat b'-0.1.

$$x=\frac{325}{-0.1}$$

Espandi \frac{325}{-0.1} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'10.

$$x=\frac{3250}{-1}$$

Frazzjoni \frac{3250}{-1} tista' tinkiteb mill-ġdid bħala -3250 bl-estrazzjoni tas-sinjal negattiv.

$$x=-3250$$
