Use the properties of operation to subtract (p-3) - (2.4+2p)

To subtract the expression (p - 3) - (2.4 + 2p), let's first distribute the negative sign across the second parentheses to remove them:

(p - 3) - (2.4 + 2p)

= p - 3 - 2.4 - 2p

Now, we just combine like terms. Let's first combine the constants (numbers without variables):

-3 - 2.4 = -5.4

Next, combine the variable terms:

p - 2p = -p

Now, putting these together:

p - 3 - 2.4 - 2p = -p - 5.4

Therefore, (p - 3) - (2.4 + 2p) simplifies to -p - 5.4.
