Let's simplify the expression step by step:
(2x - 3x - 5) - (3x + 2x + 4)
First, combine like terms within each parenthesis:
(2x - 3x - 5) = -x - 5
(3x + 2x + 4) = 5x + 4
Now, substitute these simplified expressions back into the original equation:
(-x - 5) - (5x + 4)
Distribute the negative sign to the second parenthesis:
-x - 5 - 5x - 4
Combine like terms:
(-x - 5x) + (-5 - 4) = -6x - 9
Therefore, the simplified expression is -6x - 9.
