Sa se rezolve in Q

4x=92
5x=1,05
2,(3)x=5,(3)
0,6x=1,92
0,3x=0,(3)
0,8x=4
3x=0,18
0,(3)x=1,19
2,5x=5

2.Sase determine x in multimea numerelor rationale

2x+3=17
0,5x+3=4,5
5x+0,1=2,6
0,(6)x-0,2=4,(3)
3x-0,5=2,5
2x+0,75x+2=5,75
4x+0,(2)=4,(3)

3. Rezolvati in Q

x : 1/4= 3
3x/5 : 2/9 =18
2x + 4/3 = 21/2
9x - 4/5 =1/2
3/4x + 5/6 =17/2
5/6 : x =8si1/3
5/4x + 2/3 =11/12
x + 7/2 = 3/4 +3 si1/6

va multumesc
