Suppose for any real number x, [x] denotes the greatest integer less than or
equal to x. Let L(x, y) = [x] + [y] + [x + y] and R(x, y) = [2x] + [2y]. Then it
is impossible to find any two positive real numbers x and y for whichPlease explain the solution

1) L(x, y) = R(x, y)
2) L(x, y) not equal R(x, y)
3) L(x, y) < R(x, y)
4) L(x, y) > R(x, y)
