48 = -p / 8

All you have to do is get the variable (p) by itself.

First, multiply by 8 on each side (multiplication is the opposite of division).

$${\mathtt{8}}{\mathtt{\,\times\,}}{\mathtt{48}} = {\frac{{\mathtt{\,-\,}}{\mathtt{p}}}{{\mathtt{8}}}}{\mathtt{\,\times\,}}{\mathtt{8}}$$

Multiplying by 8 cancels out the division by 8.

That gives you this:

$${\mathtt{\,-\,}}{\mathtt{p}} = {\mathtt{384}}$$

Now, to get rid of the negative sign on the variable side, divide by -1 on each side. This gives you the final answer:

$${\mathtt{p}} = -{\mathtt{384}}$$

Hope that helps!
