To solve each of these equations for x and y, we will isolate the variable on one side of the equation:

1) 9/16 - x = 1/2
x = 9/16 - 1/2
x = 9/16 - 8/16
x = 1/16

2) x + 2/3 = 7/8
x = 7/8 - 2/3
x = 21/24 - 16/24
x = 5/24

3) 1/2 + x = 23/24
x = 23/24 - 12/24
x = 11/24

4) x - 3/8 = 1/4
x = 1/4 + 3/8
x = 2/8 + 3/8
x = 5/8

5) 1/4 + y = 3/7
y = 3/7 - 1/4
y = 12/28 - 7/28
y = 5/28

6) y - 5/12 = 3/10
y = 3/10 + 5/12
y = 18/60 + 25/60
y = 43/60

7) y + 4/11 = 3/5
y = 3/5 - 4/11
y = 33/55 - 20/55
y = 13/55

8) 4/15 + y = 11/25
y = 11/25 - 4/15
y = 33/75 - 20/75
y = 13/75

So the values of x and y for each equation are:
1) x = 1/16
2) x = 5/24
3) x = 11/24
4) x = 5/8
5) y = 5/28
6) y = 43/60
7) y = 13/55
8) y = 13/75
