bonsoir g besoin d'aide pour resoudre équations svp 37+x=15 x=-37+15 x=-22 -6/5=y-11/5=? 13-a=-52 a=-13+52 a=65 7/2=-b-5/4=? 4/5m=2/3=? -2/3t=3/2=? 1+2/3

37 + x =15
x = - 37 + 15
x = - 22
---------------------------
-6/5 = y -11/5
-6/5 + 11/5 = y
+ 5/5 = y
1 = y
-------------
13 - a = - 52
 13 + 52= a  
65 = a
---------

b = -14/4-5/4
b= -19/4
----------------
4/5 m = 2/3
m = -4/5 + 2/3
m = -12/15 + 10/15
m = -2/15
---------------
-2/3 t =3/2
t = 2/3 + 3/2
t = 4/6 + 9/6
t = 13/6
--------------
1 + 2/3 = - 4 a
3/3 + 2/3 = - 4 a
3/3 + 2/3 + 12/3 = a
17/3 = a
---------------
18 = - 4 a
18 + 4 = a
22 = a

x = + 9 + 8 +15
x = 32
---------------
- 21 = x + 7 -3 x
-21- 7 = x -3x
-28 = -2x
-28 + 2= x
-26 = x
--------------------------
1/2 - x = 5/2
1/2 - 5/2 = x
-4/2 = x
-2 = x
--------------------
