    the answer is 20x - 41y

    Step-by-step explanation:

    Distribute:

    = 7 (3x-5y) + - 1 (x+6y)

    =7 (3x-5y) + - 1x + - 1x (6y)

    =7 (3x-5y) + - x + - x (6y)

    Distribute:

    =7 (3x-5y) + - x + - x + - 6y

    = 21x + - 35y + - x + - x + - 6y

    Combine like terms:

    = 21x + - 35y + - x + - 6y

    = (21x-x) + (-35y-6y)

    =20x + - 41y
