Solve[{5*a - c - d - e == 0.5,
4*b - c - e == 1,
6*c - a - b - d - e == 1,
4*d - a - c == 1,
5*e - a - b - c == 1.5},
{a, b, c, d, e}]

{{a -> 0.4130434782608696,
b -> 0.5217391304347826,
c -> 0.5000000000000001,
d -> 0.4782608695652175,
e -> 0.5869565217391305}}

Works fine here. But note the use of Equal, "==" rather than Set, "="
