Answer:
y = 13
Step-by-step explanation:
If Mr Gan packs 3 candies in each bag, he will have 4 extra candies left over. Therefore
3x + 4 = y
where 'x' represents the number of bags, and 'y' the total number of candies he has.
If Mr. Gan packs 5 candies in each bag, he will be short of 2 candies.
5x - 2 = y
To find the number of candies he has, we need to solve the system of equations ove:
3x + 4 = 5x - 2
6 = 2x
x = 3
Now, to find 'y':
5(3) - 2 = y
y = 13
Therefore, Mr. Gan has 13 candies.
