    Answer:lemon 70. Fudge 95

    Step-by-step explanation:

    3L + 2F=400

    2L + 3F = 425

    Multiply to get inverse additives.

    2 (3L + 2F) = 2 (400)

    -3 (2L + 3F) = - 3 (425)

    6L + 4F = 800

    -6L + (-9F) = - 1275

    6Ls cancel out

    4F-9F=-475

    -5F=-475

    Divide by - 5

    F=95

    Go back and put 95 in for F.

    3L + 2 (95) = 400

    3L+190=400

    Subtract 190 from each side

    3L=210.

    Divide by 3.

    L=70
