There was 10 onion rings and 5 chicken wings in the combination meal.
Let x represent the number of onion rings and y represent the number of chicken wings in the combination meal.
There are 5 more onion rings than chicken wings. Hence:
x = y + 5
x - y = 5 (1)
The combination meal has 775 total calories. Hence:
45x + 65y = 775 (2)
Solving equations 1 and 2 simultaneously gives:
x = 10, y = 5
There was 10 onion rings and 5 chicken wings in the combination meal.
