Let's solve each equation step by step:

(x-1) + (15/16) + 7 + (3/16) = 8 + (1/16) + 4 + (9/16)
x - 1 + 15/16 + 7 + 3/16 = 8 + 1/16 + 4 + 9/16
x - 1 + 15/16 + 7 + 3/16 = 8 + 1/16 + 4 + 9/16
x + 22 + 18 = 13 + 17
x + 40 = 30
x = 30 - 40
x = -10

15 + (3/28) - (4 + 11/28 + y) = 7 - 1 + (9/28)
15 + 3/28 - 4 - 11/28 - y = 7 - 1 + 9/28
15 + 3/28 - 4 - 11/28 - y = 7 - 1 + 9/28
15 - 4 + 3/28 - 11/28 - y = 6 + 9/28
11 + (-8/28) - y = 6 + 9/28
11 - 2/7 - y = 6 + 9/28
11 - 2/7 - y = 6 + 9/28
11 - 2/7 - y = 168/28 + 9/28
11 - 2/7 - y = 177/28
-y = 176/28 - 11 + 2/7
-y = 176/28 - 308/28 + 4/28
-y = -128/28
y = 128/28
y = 32/7

Therefore, the solutions are:
