```{5a - c - d - e == 0.5,
4b - c - e == 1,
6c - a - b - d - e == 1,
4d - a - c == 1,
5e - a - b - c == 1.5} // Solve

{{a -> 0.413043, c -> 0.5, d -> 0.478261, b -> 0.521739, e -> 0.586957}}

or

{5a - c - d - e == 1/2,
4b - c - e == 1,
6c - a - b - d - e == 1,
4d - a - c == 1,
5e - a - b - c == 3/2} // Solve
