Issolvi 12*900(60-x)=(80+5*4200)x-15

$$12 \times 900(60-x)=(80+5 \times 4200)x-15$$

Solvi għal x

$$x = \frac{129603}{6376} = 20\frac{2083}{6376} \approx 20.326693852$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika 12 u 900 biex tikseb 10800.

$$10800\left(60-x\right)=\left(80+5\times 4200\right)x-15$$

Uża l-propjetà distributtiva biex timmultiplika 10800 b'60-x.

$$648000-10800x=\left(80+5\times 4200\right)x-15$$

Immultiplika 5 u 4200 biex tikseb 21000.

$$648000-10800x=\left(80+21000\right)x-15$$

Żid 80 u 21000 biex tikseb 21080.

$$648000-10800x=21080x-15$$

Naqqas 21080x miż-żewġ naħat.

$$648000-10800x-21080x=-15$$

Ikkombina -10800x u -21080x biex tikseb -31880x.

$$648000-31880x=-15$$

Naqqas 648000 miż-żewġ naħat.

$$-31880x=-15-648000$$

Naqqas 648000 minn -15 biex tikseb -648015.

$$-31880x=-648015$$

Iddividi ż-żewġ naħat b'-31880.

$$x=\frac{-648015}{-31880}$$

Naqqas il-frazzjoni \frac{-648015}{-31880} għat-termini l-aktar baxxi billi testratta u tikkanċella barra -5.

$$x=\frac{129603}{6376}$$
