To simplify the expression \(5x - 7 - x - 3 + 2x - 8\), first combine like terms.
Combine the \(x\) terms: \[ 5x - x + 2x = (5 - 1 + 2)x = 6x \]
Combine the constant terms: \[ -7 - 3 - 8 = -18 \]
Putting it all together, the simplified expression is: \[ 6x - 18 \]
If you also wanted to simplify further or factor it, you could factor out a common factor, which in this case is 6: \[ 6(x - 3) \]
So, the final simplified forms are \(6x - 18\) or \(6(x - 3)\).
