Question

Rezolvati in Q ecuatia:
{-2/3-[-1/3-(2x-1/3):(-3/5)]:(-1/3)}*(-1/2)=1/2
ajutatima va rog am mare nevoie urgent 
* - inseamna imultirea:d

Answer 1

{-2/3-[-1/3-(2x-1/3):(-3/5)]:(-1/3)}*(-1/2)=1/2    
 se inmulteste cu -2
-2/3-[-1/3-(2x-1/3):(-3/5)]:(-1/3)= -1
-[-1/3-(2x-1/3):(-3/5)]:(-1/3)= -1 +2/3    
[-1/3-(2x-1/3):(-3/5)] *3= -1/3             
 impartim la 3
-1/3-(2x-1/3):(-3/5) = -1/9                           
-(2x-1/3):(-3/5) = -1/9 +1/3
(2x-1/3)*5/3 = 2/9
inmultim cu 3
(2x-1/3)*5 = 2/3
 10x-5/3 = 2/3
10x=2/3+5/3
10x=7/3
x=7/30
