Answer 1

     2
8x -4x=3x+6
 
    2
8x - 4x-3x-6=0

     2
8x -7x -6=0


B)8m-4+3m-8m-2=0
    8m-8m+3m-2-4=0
       
   R=3m-6=0
           3m=6
             m=2

C)5y+(10-5)=0
    5y+5=0
       5y=-5
          y=-1

D) (z+9)+(z+5)+(z+7)-8=0
       z+9+z+5+z+7-8=0
        z+z+z+5+7+9-8=0
            3z+13=0
              3z=-13
                z=13/3

E)3a+9-4a-2=9
    3a-4a=9-9-2
       -a=-2
        a=2
