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?

Simplifying
2 + - 1 (4p + 3) = - 3 (p + 2) + - 1 (2p + 3)
Reorder the terms:
2 + - 1 (3 + 4p) = - 3 (p + 2) + - 1 (2p + 3)
2 + (3 * - 1 + 4p * - 1) = - 3 (p + 2) + - 1 (2p + 3)
2 + (-3 + - 4p) = - 3 (p + 2) + - 1 (2p + 3)
Combine like terms: 2 + - 3 = - 1
-1 + - 4p = - 3 (p + 2) + - 1 (2p + 3)
Reorder the terms:
-1 + - 4p = - 3 (2 + p) + - 1 (2p + 3)
-1 + - 4p = (2 * - 3 + p * - 3) + - 1 (2p + 3)
-1 + - 4p = (-6 + - 3p) + - 1 (2p + 3)
Reorder the terms:
-1 + - 4p = - 6 + - 3p + - 1 (3 + 2p)
-1 + - 4p = - 6 + - 3p + (3 * - 1 + 2p * - 1)
-1 + - 4p = - 6 + - 3p + (-3 + - 2p)
Reorder the terms:
-1 + - 4p = - 6 + - 3 + - 3p + - 2p
Combine like terms: - 6 + - 3 = - 9
-1 + - 4p = - 9 + - 3p + - 2p
Combine like terms: - 3p + - 2p = - 5p
-1 + - 4p = - 9 + - 5p
Solving
-1 + - 4p = - 9 + - 5p
Move all terms containing p to the left, all other terms to the right.
Add '5p' to each side of the equation.
-1 + - 4p + 5p = - 9 + - 5p + 5p
Combine like terms: - 4p + 5p = 1p
-1 + 1p = - 9 + - 5p + 5p
Combine like terms: - 5p + 5p = 0
-1 + 1p = - 9 + 0
-1 + 1p = - 9
Add '1' to each side of the equation.
-1 + 1 + 1p = - 9 + 1
Combine like terms: - 1 + 1 = 0
0 + 1p = - 9 + 1
1p = - 9 + 1
Combine like terms: - 9 + 1 = - 8
1p = - 8
Divide each side by '1'.
p = - 8
Simplifying
p = - 8
