Issolvi (x+90)*89.5=100x+8000

$$(x+90) \times 89.5=100x+8000$$

Solvi għal x

$$x = \frac{110}{21} = 5\frac{5}{21} \approx 5.238095238$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika x+90 b'89.5.

$$89.5x+8055=100x+8000$$

Naqqas 100x miż-żewġ naħat.

$$89.5x+8055-100x=8000$$

Ikkombina 89.5x u -100x biex tikseb -10.5x.

$$-10.5x+8055=8000$$

Naqqas 8055 miż-żewġ naħat.

$$-10.5x=8000-8055$$

Naqqas 8055 minn 8000 biex tikseb -55.

$$-10.5x=-55$$

Iddividi ż-żewġ naħat b'-10.5.

$$x=\frac{-55}{-10.5}$$

Espandi \frac{-55}{-10.5} billi timmultiplika kemm in-numeratur kif ukoll id-denominatur b'10.

$$x=\frac{-550}{-105}$$

Naqqas il-frazzjoni \frac{-550}{-105} għat-termini l-aktar baxxi billi testratta u tikkanċella barra -5.

$$x=\frac{110}{21}$$
