Question 870923: How do you evaluate the equation |p| - |3q|? p=-2 and q= 3
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
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

-7

So, |-2| - |3(3)| = -7

and, |p| - |3q| = -7 when p = -2 and q = 3
