To solve these equations, we'll need to simplify each one step by step:

9 - 7y = 25 - 3y
-4y = 16
y = -4

-2n = 5.6n
-2n - 5.6n = 0
-7.6n = 0
n = 0

2(11 - 4a) = 3 - (5a + 2)
22 - 8a = 3 - 5a - 2
22 - 8a = 1 - 5a
-3a = -21
a = 7

3(-5 + c) - 2(c - 4) = 2 - 7(c - 1)
-15 + 3c - 2c + 8 = 2 - 7c + 7
c - 7c - 30 + 8 = 9
-6c = 31
c = -31/6

Therefore, the solutions to the equations are:
