    Floor function

    Solve for x:

    \lfloor x\rfloor+\lfloor 5x\rfloor+\lfloor 10x\rfloor+\lfloor 20x\rfloor=36k+35

    where 'k' is an integer and \lfloor x\rfloor denotes the floor function.

    The standard notation for the floor function can be achived in LaTeX by \lfloor \rfloor as so: \lfloor \ \rfloor

    Start by writing x=n+\varepsilon where n=\lfloor x\rfloor and 1>\varepsilon\ge 0.
