I'll begin by rewriting this with more space

-31= 8 - 6p - 7

Hope I got it right.

The first obvious thing to me is that the right side has two constants in it: 8 - 7  So I will take care of that first.

-31 = 1 - 6p

Next I will get rid of the lone "1" on the right by subtracting 1 from both sides of the equation

-32 = -6p

and then make it all simpler by multiplying both sides by negative one

32 = 6p

and then divide both sides by 6 to get

32/6 = p

So the value of p that makes the original equation true is 32/6, or "five and one third"
