Issolvi 151*1.8x=100left(15*2.5+left(x-15right)3.3right)

$$151 \cdot 1.8x = 100 \left( 15 \cdot 2.5+ \left( x-15 \right) 3.3 \right)$$

Solvi għal x

$$x = \frac{2000}{97} = 20\frac{60}{97} \approx 20.618556701$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika 151 u 1.8 biex tikseb 271.8.

$$271.8x=100\left(15\times 2.5+\left(x-15\right)\times 3.3\right)$$

Immultiplika 15 u 2.5 biex tikseb 37.5.

$$271.8x=100\left(37.5+\left(x-15\right)\times 3.3\right)$$

Uża l-propjetà distributtiva biex timmultiplika x-15 b'3.3.

$$271.8x=100\left(37.5+3.3x-49.5\right)$$

Naqqas 49.5 minn 37.5 biex tikseb -12.

$$271.8x=100\left(-12+3.3x\right)$$

Uża l-propjetà distributtiva biex timmultiplika 100 b'-12+3.3x.

$$271.8x=-1200+330x$$

Naqqas 330x miż-żewġ naħat.

$$271.8x-330x=-1200$$

Ikkombina 271.8x u -330x biex tikseb -58.2x.

$$-58.2x=-1200$$

Iddividi ż-żewġ naħat b'-58.2.

$$x=\frac{-1200}{-58.2}$$

Espandi \frac{-1200}{-58.2} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'10.

$$x=\frac{-12000}{-582}$$

Naqqas il-frazzjoni \frac{-12000}{-582} għat-termini l-aktar baxxi billi testratta u tikkanċella barra -6.

$$x=\frac{2000}{97}$$
