Step-by-step explanation:
This can be solved by working backwards.
7 is one more than half the number of invitations.
Subtract 1. 6 is half the number of invitations.
Double.
12 is the full number of invitations.
Algebra (if you must!):
x = number of invitations
x/2 + 1 = 7
Subtract 1.
x/2 = 6
Multiply by 2.
x = 12
All you need to do is 8 divided by 6. When you do so you get: 1.3 which could also be written as 1 3/8.
So each person gets 1 whole piece and 3/8 of another piece.
