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

### Instruction:
Josh has 85 marbles. There are three times as many blue marbles as red while the rest are yellow. If there are 14 red marbles, how many yellow marbles are there?

### Response:
There are 14 x 3 = <<14*3=42>>42 blue marbles.
There are a total of 14 + 42 = <<14+42=56>>56 marbles that are not yellow.
Therefore, 85 - 56 = <<85-56=29>>29 marbles are yellow.
