Passi biex Issolvi l-Ekwazzjoni Lineari

Ikkalkula 10 bil-power ta' -19 u tikseb \frac{1}{10000000000000000000}.

$$7.2=\left(-x\right)\times \frac{1}{10000000000000000000}$$

Ibdel in-naħat sabiex it-termini varjabbli kollha jkunu fuq in-naħa tax-xellug.

$$\left(-x\right)\times \frac{1}{10000000000000000000}=7.2$$

Immultiplika ż-żewġ naħat b'10000000000000000000, ir-reċiproku ta' \frac{1}{10000000000000000000}.

$$-x=7.2\times 10000000000000000000$$

Immultiplika 7.2 u 10000000000000000000 biex tikseb 72000000000000000000.

$$-x=72000000000000000000$$

Immultiplika ż-żewġ naħat b'-1.
