Based on the following question, write an entirely new question which is about a related topic but asks something completely different:

Original Question: The sum of 7 and u is 14.
Original Answer: 7+u=14; u=7.

New Question: Jack has 10 more pairs of socks than Jill. If Jack has 26 pairs of socks, how many pairs of socks does Jill have?

To find the answer to the new question, we can set up an equation based on the information given. Here's how you can approach it:

Let's use the variable "j" to represent the number of pairs of socks that Jill has. According to the information given, Jack has 10 more pairs of socks than Jill. So, we can express this as "j + 10" to represent the number of pairs of socks that Jack has.

Since we're told that Jack has 26 pairs of socks, we can set up the equation as follows:

j + 10 = 26

To find the value of "j," we can isolate the variable by subtracting 10 from both sides of the equation:

j + 10 - 10 = 26 - 10

This simplifies to:

j = 16

Therefore, Jill has 16 pairs of socks.
