Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Kwanza tafuta idadi ya jozi za viatu vya ndani ambazo Nancy anazo: jozi sita + jozi tisa = <<6+9=15>>15 jozi
Kisha ongeza idadi hiyo kwa idadi ya jozi za buti anazo: jozi 15 + jozi sita = <<15+6=21>>21 jozi
Kisha mara tatu idadi hiyo ili kupata idadi ya jozi za viatu vya kisigino anazo: jozi 21 * mara tatu = <<21*3=63>>63 jozi
Kisha ongeza idadi ya jozi za kila aina ya viatu anazo: jozi 15 + jozi sita + jozi 63 = <<15+6+63=84>>84 jozi
Kisha mara idadi ya jozi kwa 2 ili kupata idadi ya viatu binafsi anavyo: jozi 84 * viatu 2/jozi = 168 viatu
