21 = -2p - 5 what number does p represent?
svetoff [14.1K]

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 :)
