Trevor is a comic book illustrator. In the past three months, he has drawn 220 pages of the comic. The comic he illustrates releases a new issue once a month. The first and second months’ issues were the same number of pages, but the third month’s issue was four pages longer than either of the others. How many pages was the first issue of the comic?
Let P be the number of pages of the first issue of the comic.
The second issue is the same number of pages, so the first and second issues are P + P = 2P pages.
The third issue is 4 pages longer, so it is P + 4 pages.
All three issues are 2P + P + 4 = 3P + 4 = 220 pages long.
Thus, 3P = 220 - 4 = 216 pages.
Therefore, the first issue of the comic was P = 216 / 3 = <<216/3=72>>72 pages.

Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
You are solving math problems. Here are some examples of how to solve the task:

Lars owns a bakeshop. She can bake 10 loaves of bread within an hour and 30 baguettes every 2 hours. If she bakes 6 hours a day, how many breads does she makes?Lars can bake 10 x 6 = <<10*6=60>>60 loaves of bread every day.
She can also bake 30 x 3 = <<30*3=90>>90 baguettes every day.
Therefore the total bread she can bake is 60 + 90 = <<60+90=150>>150.

Maddy is in college for 8 semesters. She needs 120 credits to graduate. If each class is 3 credits, how many classes does she need to take per semester?120 credits / 3 credits is <<120/3=40>>40.
40 credits/ 8 semester = <<40/8=5>>5 classes per semester.
Maddy needs to take 5 classes per semester

Now, solve this next question in the style of the above examples:

Trevor is a comic book illustrator. In the past three months, he has drawn 220 pages of the comic. The comic he illustrates releases a new issue once a month. The first and second months’ issues were the same number of pages, but the third month’s issue was four pages longer than either of the others. How many pages was the first issue of the comic?

### Response:
Let P be the number of pages of the first issue of the comic.
The second issue is the same number of pages, so the first and second issues are P + P = 2P pages.
The third issue is 4 pages longer, so it is P + 4 pages.
All three issues are 2P + P + 4 = 3P + 4 = 220 pages long.
Thus, 3P = 220 - 4 = 216 pages.
Therefore, the first issue of the comic was P = 216 / 3 = <<216/3=72>>72 pages.
