Ultimately, you want the <em>variable</em> p on one side of the equals sign, and the <em>value</em> of p on the other. First, get rid of the parenthesis by <em>distributing. </em>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. <em> </em>So you have: 2-4p-3 = -3p-6-2p-3 <em> </em>Next, <em>Combine like terms. </em> Can you take it from there?<em> </em>
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
