Answer: P represents -13
Step-by-step explanation:
Since a negative x negative + positive, we know that p has to be a negative.
For me, I added both 21 and -5 (though I made it into a positive), and got 26.
What number times -2 is positive 26?
So, you divide 26/-2, which then becomes -13.
Thus, p=-13 :)
