    Let's simplify step-by-step.

    2 (a-3) + 4b - 2 (a-b - 3) + 5

    Distribute:

    = (2) (a) + (2) (-3) + 4b + (-2) (a) + (-2) (-b) + (-2) (-3) + 5

    = 2a + - 6 + 4b + - 2a + 2b + 6 + 5

    Combine Like Terms:

    = 2a + - 6 + 4b + - 2a + 2b + 6 + 5

    = (2a + - 2a) + (4b + 2b) + (-6 + 6 + 5)

    = 6b + 5

    Answer : = 6b+5
