9. Rezolvati , in multimea numerelor naturale , ecuatiile:
a) 4x + 2x + 5 - 6x = 7
b) 2x + 3x + 3 - 5x = 3
c) 2(x+2) - 3 +5x- 7x = 2
d) 3x + 2( x+5 ) +7 = 11 + 5x + 6
e) 5x+8x+ 2 la puterea a 3 = 8+13x+7
f) 2( x + 4 ) + 3 ( 2x+3 ) + 5 = 10+8x+12
Va rooooogggggg repede ! Nustiu ! Si nu vreau doar raspunsurile , vreau intreaga rezolvare ! Multumesc mult brainly.ro

A)4x+2x+5-6x=7
   6x+5-6x=7
   5=7 (Fals)
b)2x+3x+3-5x=3
   5x+3-5x=3
    3=3
c)2x+4-3+5x-7x=2
  7x+1-7x=2
  1=2 (Fals)
d)3x+2x+10+7=11+5x+6
  5x+17=17+5x
e)5x+8x+2³=8+13x+7
   13x+8=13x+15
    8=15 (Fals)
f)2x+8+6x+9+5=10+8x+12
  8x+22=8x+22
