a) 2x+5-5x=-1     

b)5+6x=5x+2

c)x+2x-1-3=x

d)-3x+10=2x8+1

e)5x.5+x=9+x

f)7x-4-x=2x+8.3x

Answer 1

 a) 2x+5-5x=-1                      c)x+6x=5x+2                     e)5x.5+x=9+x
     2x-5x=-1-5                          x+6x-5X=2                         5x+x-x=9-5
     3x=-6/3                               2x=2                                  5x=4
       x=-2                                   x=2/2                                  x=4/5
                                                 x=2


b)5+6x=5x+2                           d) nao entendi a sua pergunta
   6x-5x=2-5                              
   1x=3
     x=3/1
     x=3

Answer 2

a) 2x+5-5x=-1
-3x = -1 -5
-3x = -6
x=6/3   
x=2

 b)5+6x=5x+2
6x -5x = 2 -5
x=-3

c)x+2x-1-3=x
 x+2x -x = 3 +1
=0    
            
d)-3x+10=2x8+1
-3x -2x = ?????

e)5x.5+x=9+x  
 25x + x -x = 9
 25x =9
 x=9/25
              
 f)7x-4-x=2x+8.3x
7x -x -2x -24x = 4 
-20x =4
x= - 4/20
x=-1/5
