Question 870923
We're told that p = -2. So wherever you see a 'p', you replace it with -2.
Similarly, we know q = 3. So you replace all copies of q with 3.
After that, you evaluate using PEMDAS



|p| - |3q|



|-2| - |3q|



|-2| - |3(3)|



|-2| - |9|



2 - 9



<font color="red">-7</font>



So, |-2| - |3(3)| = <font color="red">-7</font>



and, |p| - |3q| = <font color="red">-7</font> when p = -2 and q = 3
