The teacher asked Jenny's class to solve the equation $5x - 6 = 4x + 9$. Jenny copied the coefficient of $x$ on the right-hand side incorrectly and wrote down a different equation. Jenny correctly determined that her equation had no solutions. What was the coefficient of $x$ on the right-hand side of Jenny's equation?
