Question

Resolva as equações:
a) 4x - 8 = 2x + 6
b) 7x + 1 = 6x + 6
c) 5x - 3 = 2x - 9
d) 4x - 7 + x = 1
e) 3 - 2x = 4x

Answer 1

a) 4x-8=2x+6
    4x+2x=6+8
    6x=14
      x= 14/6
b) 7x+1=6x+6
   7x+6x=6+1
   13x= 7
      x=7/13
c) 5x-3=2x-9
   5x+2x=-9+3
   7x=-6
     x=-6/7
d) 4x-7+x=1
    4x+x=1+7
    5x=8
      x=8/5
e) 3-2x=4x
    -2x+4x=-3
    2x=-3
      x=-3/2
Espero ter ajudado.
