Linda performed 5 haircuts on Monday.

Given that the 17 haircuts performed on Friday were 7 more than twice the haircuts on Monday (h), we can come up with the following equation:
2h + 7 = 17

By performing the various operations,
2h = 17 - 7
2h = 10
h = 10/2
h = 5
We can conclude that h (the number of haircuts Linda performed on Monday) is equal to 5.
