14x\times \frac{4}{5}+\left(210-14x\right)\times \frac{90}{100}=182
Naqqas il-frazzjoni \frac{80}{100} għat-termini l-aktar baxxi billi testratta u tikkanċella barra 20.
\frac{14\times 4}{5}x+\left(210-14x\right)\times \frac{90}{100}=182
Esprimi 14\times \frac{4}{5} bħala frazzjoni waħda.
\frac{56}{5}x+\left(210-14x\right)\times \frac{90}{100}=182
Immultiplika 14 u 4 biex tikseb 56.
\frac{56}{5}x+\left(210-14x\right)\times \frac{9}{10}=182
