    a/m - b = c for m

    Add b to both sides:
    a/m - b + b = c + b

    Cancel b on both sides:
    a/m = c + b

    Multiply each side by m:
    am/m = m(c + b)

    Cancel the m's on the left side:
    a = m(c + b)

    Divide each side by (c + b)
    a/(c + b) = m(c + b)/(c + b)

    Cancel the (c + b) on the right side, and we get:
    m = a/(c + b)
