    Step-by-step explanation:

    16 - 2r = - 3r + 6r + 1

    Add the like terms in the RHS

    16 - 2r = 3r + 1

    Add 2r to both the sides

    16 - 2r + 2r = 3r + 1 + 2r

    16 = 5r + 1

    Subtract 1 from both sides

    16 - 1 = 5r + 1 - 1

    15 = 5r

    Divide both sides by 5

    15/5 = 5r/5

    3 = r

    r = 3
