Question 185
Find the number of integer solutions of the equation
$$
\left\lfloor \frac{x}{7} \right\rfloor = \left\lfloor \frac{x}{12} \right\rfloor + \left\lfloor \frac{x}{17} \right\rfloor.
$$
$$
\left\lfloor \frac{x}{7} \right\rfloor = \left\lfloor \frac{x}{12} \right\rfloor + \left\lfloor \frac{x}{17} \right\rfloor.
