Nancy has six pairs of boots, nine more pairs of slippers than boots, and a number of pairs of heels equal to three times the combined number of slippers and boots. How many shoes (individual shoes, not pairs) does she have? Let's think step by step and output the final answer after "####".

First find how many pairs of slippers Nancy has: 6 pairs + 9 pairs = <<6+9=15>>15 pairs
Then add that number to the number of pairs of boots she has: 15 pairs + 6 pairs = <<15+6=21>>21 pairs
Then triple that number to find how many pairs of heels she has: 21 pairs * 3 = <<21*3=63>>63 pairs
Then add the number of pairs of each kind of shoe she has: 15 pairs + 6 pairs + 63 pairs = <<15+6+63=84>>84 pairs
Then multiply the number of pairs by 2 to find the number of individual shoes she has: 84 pairs * 2 shoes/pair = <<84*2=168>>168 shoes
#### 168
