a. x -12 + 16 -2x =14 ; -x = 14 -4 ; -x = 10 , x = - 10
b . x + 25 -x +12 =13 ; 37=13 ecuatia nu are solutie
c . 2x -6 =14 -2x ; 2x + 2x = 14+6 ; 4x = 20 ; x =20:4 =5
d. 44 -x -x +35 =0 ; -2 x = -79 ; x = 79 :2 =39,5∉Z

x -12 + 16 -2x =14
-x = 10
x = - 10
x + 25 -x +12 =13
37=13 ecuatie impoibila
2x -6 =14 -2x
2x + 2x = 14+6
4x = 20 x=5
44 -x-x +35 =0 79-2x=0
