    Solve for x:

    5 – 3 x = 12 x + 4

    Subtract 12 x from both sides:

    5 + (-3 x – 12 x) = (12 x – 12 x) + 4

    -3 x – 12 x = -15 x:

    -15 x + 5 = (12 x – 12 x) + 4

    12 x – 12 x = 0:

    5 – 15 x = 4

    Subtract 5 from both sides:

    (5 – 5) – 15 x = 4 – 5

    5 – 5 = 0:

    -15 x = 4 – 5

    4 – 5 = -1:

    -15 x = -1

    Divide both sides of -15 x = -1 by -15:

    (-15 x)/(-15) = (-1)/(-15)

    (-15)/(-15) = 1:

    x = (-1)/(-15)

    Multiply numerator and denominator of (-1)/(-15) by -1:

    Answer:  x = 1/15
