    r=3

    Step-by-step explanation:

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

    Combine like terms

    16-2r = 3r + 1

    Add 2r to each side

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

    16 = 5r+1

    Subtract 1 from each side

    16-1 = 5r+1-1

    15 = 5r

    Divide by 5 on each side

    15/5 = 5r/5

    3 = r

    r=3

    Step-by-step explanation:

    Simplify the expression

    16-2r=3r+1

    isolate r by adding 2r to both sides

    16=5r+1

    isolate the numbers by subtracting 1 from both sides

    15=5r

    divide both sides by 5 to completely isolate r

    r=3
