To simplify the expression \(3(a - 2b) - 2a + b\), follow these steps:

  1. Distribute the 3 into the first part of the expression: \[ 3(a - 2b) = 3a - 6b \]

  2. Now, substitute back into the expression: \[ 3a - 6b - 2a + b \]

  3. Combine like terms:

    • For \(a\) terms: \(3a - 2a = 1a\) or simply \(a\)
    • For \(b\) terms: \(-6b + b = -5b\)

Putting it all together, we get: \[ a - 5b \]

Thus, the expression equivalent to \(3(a - 2b) - 2a + b\) is: \[ \boxed{a - 5b} \]
