    r = (-3) / 32

    Step-by-step explanation:

    Solve for r:

    -3 (6 r + 1) = 14 r

    Expand out terms of the left hand side:

    -18 r - 3 = 14 r

    Subtract 14 r from both sides:

    (-18 r - 14 r) - 3 = 14 r - 14 r

    -18 r - 14 r = - 32 r:

    -32 r - 3 = 14 r - 14 r

    14 r - 14 r = 0:

    -32 r - 3 = 0

    Add 3 to both sides:

    (3 - 3) - 32 r = 3

    3 - 3 = 0:

    -32 r = 3

    Divide both sides of - 32 r = 3 by - 32:

    (-32 r) / (-32) = 3 / (-32)

    (-32) / (-32) = 1:

    r = 3 / (-32)

    Multiply numerator and denominator of 3 / (-32) by - 1:

    Answer: r = (-3) / 32
