Question 11053
1) 7y - 7 = -1 
7y-7+7 = -1 + 7
7y = 6 
2) 5=4y/3+12 
3) 2(x-3)= 6 
4) 7x-4= 0 
5) 3/2x+3 = 5 
6) 3(x-5) = 15x 
7) 4(x-1)-3(x+1) = 2 
8) 4(x-2)- (3-x) = 3(x-1) 
9) x/3 + x/4 + 7/12


1. 7y-7=-1
     +7 +7
  ---------
      7y= 6
      -   -
      7   7

y= 6
   -
   7

2. not sure

3. 2(x-3)= 6
   2x-6= 6
     +6 +6
  -----------
     2x=12
     -  --
     2   2

      x=6

4. 7x-4= 0 
     +4 +4
  ----------
     7x=4
     -  -
     7  7

     x=4/7

5-9...not sure
