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

### Instruction:
 Micah bought envelopes to send, and depending on the weight of the envelope he will need more stamps. If an envelope weighs more than 5 pounds, he will need 5 stamps. If it weighs less than that, it will only need 2 stamps. If he bought 52 stamps with 6 envelopes that weigh less than 5 pounds, how many envelopes in total did Micah need to buy?


### Response:
 Micah a dû acheter 6 enveloppes * 2 timbres = <<6*2=12>>12 timbres pour 6 enveloppes de moins de 5 livres.
Il a donc 52 timbres au total - 12 timbres pour moins de 5 livres = 40 timbres pour plus de 5 livres.
Cela signifie qu'il a 40 timbres / 5 timbres par enveloppe = <<40/5=8>>8 enveloppes qui pèsent plus de 5 livres.
Il a donc acheté 8 enveloppes + 6 enveloppes = <<8+6=14>>14 enveloppes.
