Issolvi 5*20+(x-5)*4=(5*20+44)*0.9

$$5 \times 20 + ( x - 5 ) \times 4 = ( 5 \times 20 + 44 ) \times 0.9$$

Solvi għal x

$$x=12.4$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Immultiplika 5 u 20 biex tikseb 100.

$$100+\left(x-5\right)\times 4=\left(5\times 20+44\right)\times 0.9$$

Uża l-propjetà distributtiva biex timmultiplika x-5 b'4.

$$100+4x-20=\left(5\times 20+44\right)\times 0.9$$

Naqqas 20 minn 100 biex tikseb 80.

$$80+4x=\left(5\times 20+44\right)\times 0.9$$

Immultiplika 5 u 20 biex tikseb 100.

$$80+4x=\left(100+44\right)\times 0.9$$

Żid 100 u 44 biex tikseb 144.

$$80+4x=144\times 0.9$$

Immultiplika 144 u 0.9 biex tikseb 129.6.

$$80+4x=129.6$$

Naqqas 80 miż-żewġ naħat.

$$4x=129.6-80$$

Naqqas 80 minn 129.6 biex tikseb 49.6.

$$4x=49.6$$

Iddividi ż-żewġ naħat b'4.

$$x=\frac{49.6}{4}$$

Espandi \frac{49.6}{4} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'10.

$$x=\frac{496}{40}$$

Naqqas il-frazzjoni \frac{496}{40} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 8.

$$x=\frac{62}{5}$$
