[tex] \frac{x+2}{12} = \frac{5}{6} [/tex]
[tex]x=8[/tex]
[tex] \frac{8+2}{12} = \frac{10}{12}= \frac{5}{6} ;[/tex]

[tex]\mathtt{\frac{x+2}{12}= \frac{5}{6}} \\ \\ \mathtt{Facem~produsul~mezilor~cu~al~extremilor:} \\ \\ \mathtt{5*12=6(x+2)} \\ \\ \mathtt{60=6(x+2)} \\ \\ \mathtt{x+2=10} \\ \\ \boxed{\mathtt{x=8}}[/tex]
