Final answer:
To simplify the given equation, combine like terms on both sides and isolate 'p' to find the solution.
Step-by-step explanation:
To simplify the equation, we need to combine like terms on both sides. Let's start by combining the 'p' terms on the right side:
7p + 4 = -p + 9 + 2p + 3p
Combining like terms, we get:
7p + 4 = 6p + 9
Next, let's simplify further by subtracting 6p from both sides:
7p - 6p + 4 = 6p - 6p + 9
This simplifies to:
p + 4 = 9
To isolate 'p', we subtract 4 from both sides:
p + 4 - 4 = 9 - 4
This simplifies to:
p = 5
Therefore, the simplified form of the equation is 'p = 5'.
