 \frac{x-3}{3} + \frac{x}{2} =5⇔ \frac{x-3}{3} + \frac{x}{2} =5⇔ \frac{2x-6+3x}{6} =5⇔ \frac{2x+3x-6}{6} =5 \frac{5x-6}{6} =5⇔ \frac{5x-6=5}{6}  \frac{5x=5+6}{6}  \frac{5x=11}{6}  \frac{x= \frac{11}{5} }{6} x= \frac{2.2}{6} ⇔x=1
S=1

de la acest pas era asa: 5x-6=30 => 5x=36 => x=36/5=7.2
deci x este 7.2 ,nicidecum 1 :)
si mie mi-a dat asa la inceput si am zis ca e gresit,haha
bravo ;)
Asemenea! Multumesc mult! :D
