The club has 56 old men.
Let x = number of old men
Then x-16 = number of young men (the old men outnumber the young men by 16)
7x = 9(x-16) +32 (7 times the # old men is 32 more than 9 times the # young men)
7x = 9x - 144 + 32
7x = 9x - 112
7x + 112 = 9x - 112 + 112
7x + 112 = 9x
7x - 7x + 112 = 9x - 7x
112 = 2x
56 = x (the # of old men)
