Răspuns :

[tex]\dfrac{5}{6}x - \dfrac{1}{2} = 1,25 \Leftrightarrow \dfrac{5}{6}x - \dfrac{1}{2} = \dfrac{125}{100} \Leftrightarrow \dfrac{5}{6}x - \dfrac{1}{2} = \dfrac{5}{4} |_{\cdot12} \Leftrightarrow 10x - 6 = 15 \\\;\\ \Leftrightarrow 10x = 21 \Leftrightarrow x=\dfrac{21}{10} \Leftrightarrow x=2,1 \\\;\\ .[/tex]
