    Step-by-step explanation:

    A.) 2a+4b-c: Replacing a with 2, b with 3 and c with 4, we get:

    2 (2) + 4 (3) - (4) = 4 + 12 - 4 = 12

    B.) 6 (a+c) - b: Replacing a with 2 and c with 4, we get 6 (2 + 4) - 3.

    The work inside parentheses should be done first, resulting in 6 (6) - 3.

    This comes out to 33.
