e) x-6=5x+8-x
preciso com a conta

Answer 1

a) 7x+3=2x+23 
   7x-2x=23-3
   5x=20
     x=20/5
      x=4
b) 2m-5=14-3m
   2m+3m=14+5
   5m=19
    m=19/5
c) x+2=5x-2 
   2+2=5x-x
   4=4x
   x=4/4
   x=1
d) x+3=4x-1 
   3+1=4x-1
   4=3x
   x=4/3
e) x-6=5x+8-x
    x-5x+x=8+6
    2x-5x=14
    -3x=14
       x=14/-3
