Answer: There are 152 apples.

The explanation is shown below:

- You need to write the following three equations, where a is the the number of apples, p is the number of pears and o is the number of oranges:

1) a+p=184

2) a+o=248

3) o=3p

-  You must substitute the equation 3) into the equation 2):

 a+3p=248

- Now, you need to solve for p in the equation 1) and then you must substitute it into a+3p=248:

p=184-a

a+3(184-a)=248

- Solve for a, as following:

a+552-3a=248\\-2a=-304\\a=\frac{-304}{-2}\\a=152

- Therefore, there are 152 apples.
