    Step-by-step explanation:

    (-5y+1) - (3y+2) = - 9

    (-5y-3y) + (1-2) = - 9

    -8y - 1 = - 9

    -8y = - 8

    y = 1

    the difference between the 2 expressions is

    - 5y + 1 - (3y + 2) = - 9

    - 5y + 1 - 3y - 2 = - 9

    - 8y - 1 = - 9 (add 1 to both sides)

    - 8y = - 8 (divide both sides by - 8)

    y = 1
