Ultimately, you want the variable p on one side of the equals sign, and the value of p on the other.
First, get rid of the parenthesis by distributing.
There is an invisible -1 in front of the first and last set of parenthesis, and a one times any number is the number itself, so you are essentially distributing the negative sign.
So you have: 2-4p-3 = -3p-6-2p-3
Next, Combine like terms.
Can you take it from there?
