p=3

Explanation:

First, you always want to get like terms on one side. Here we have constants and p as our terms. If we subtract 8 from both sides, we will get:

-31-8=-6p-7p

Then, we can combine the like terms. We can determine that -31-8 is -39 and -6p-7p is -13p. We can then rewrite the equation as:

-39=-13p

Since we are trying to solve for p, we can divide both sides by a constant of -13 to isolate the variable p. When we divide on the right side, we are left with just p. When we divide on the left side, we get (-39)/-13, which is 3. Thus, writing out equation again, we see that:

3=p

By using the reflexive property of equations, we can say that:

p=3.
