Simple Solve command not working.

My command:

solve('0.5 - 25/8 + 4*E = 0',E)

The error:

Warning: Explicit solution could not be found. > In solve at 83

ans =

[ empty sym ]

W...what? Is this a joke?

I used "syms E" first off.

Funny thing is, if I change the E to an x, it works. WTF?

When you use solve with a string input, it interprets the "E" as exp(1). Try this:

solve('x = E', 'x')

If you really want to call your variable E, then remove the apostrophes:

syms E
solve(0.5 - 25/8 + 4*E == 0,E)
