Facetimi si mie asta va rog!!
Îmi este pe mâine!!

Answer 1

1. x+5/3=-1/2
x=-1/2-5/3=-3/6-10/6=-13/6
2. x-5/4=1/8
x=1/8+5/4=(1+10)/8=11/8
3.4/9 +x= 1
x=1-4/9=5/9
4.2x/3=-3/5
x=-9/10
5. 3/7 -x=5/14
x=3/7-5/14=1/14
6. 4x/5=-1/3  x=-5/12
7. x×2,4=-1/3 
x=-1/3 :2,4 =-1/4 ×10/24=-10/96=-5/48
8.-5/6=-10x/3   
x=15/60=1/4
9. 0,01=0,1x
x=0,01:0,1=0,1
10 x:3/5 =-1/6
5x/3=-1/6
10x=-1
x=-1/10
11. x:0,2=-0,5
x=-0,5 ×0,2=-0,1
12. -5/7 :x =2/7
-5:x=2
x=-5/2
13. (0,01)² :x=1
0,0001:x=1
x=0,0001=1/1000
