Simplify (3x − 8) + (2x + 5) − (4x − 8)

To simplify the given expression, let's combine like terms:

(3x - 8) + (2x + 5) - (4x - 8)

First, let's remove the parentheses:

= 3x - 8 + 2x + 5 - 4x + 8

Next, combine like terms:

= (3x + 2x - 4x) + (-8 + 5 + 8)

Simplifying further:

= (1x) + (5)

= x + 5

Therefore, the simplified expression is x + 5.
