x = almond cookies
3x = chocolate cookies.
From the condition, we have THESE two equations
x = 3n + 3 (1) (n = the number of friends)
3x = 4n + 24 (2)
Multiply equation (1) by 3 (both sides). You will get
3x = 9n + 9.
Substitute it into equation (2). You will get
9n + 9 = 4n + 24.
It implies
9n - 4n = 24 - 9
5n = 15
n = 15/5 = 3.
So, there are 3 friends.
