2021/063) Solve x+\lfloor 2x\rfloor +\lfloor 3x\rfloor=7

 Because RHS is integer so LHS is integer


As \lfloor 2x \rfloor and \lfloor 3x \rfloor are integers so x is integer so   \lfloor 2x \rfloor = 2x and  \lfloor 3x \rfloor = 3x


so x + 2x + 3x = 6x = 7 so x = \frac{7}{6} which is not integer so NO solution
