33 - x = a              2 -| a
33 - x != 0 mod 2
x != 1 mod 2
x = 0 mod 2 -> x is even


128 - x = 2b            2 -| b
128 - x != 0 mod 4
x != 0 mod 4 -> 4 -| x

130 - x = 32c           2 -| c
130 - x != 0 mod 64
x != 2 mod 64
130 - x = 0 mod 32
x = 2 mod 32
combine to get:
x = 34 mod 64

98 - x = d              3 -| d
98 - x != 0 mod 3
x != 2 mod 3

162 - x = 3n            3 -| n
x = 0 mod 3
162 - x != 0 mod 9
x != 0 mod 9

x = 3 mod 9
or
x = 6 mod 9

x is divisible by 3 but not divisible by 9

354 - x = 3n            3 -| n
x = 0 mod 3 (already know)
354 - x != 0 mod 9
x != 3 mod 9
x = 6 mod 9

x = 34 mod 64
x = 6 mod 9
x = 546 mod 576
