Answer provided by our tutors
Let 'x' represent the number of days that the boy will eat 18 sweets per day.
This means that the total number of sweets is 18x.
If he eats 16 sweets per day the sweets will last 2 days longer or (x + 2) days. Then the total number of sweets can be written as: 16(x + 2).
Now we can write the following equation:
18x = 16(x + 2)
