Simple Solving Question

[thescreensavers]

in CAS mode

If I input for example solve(0.25= 1/1.8(x)) I get [] as my answer

if I input the same thing but instead of 1/1.8 I put in 0.555 it then spits out the answer.

Why is that?

Seems to work okay for me either way - even with various CAS Settings...

You might have forgot the * after the (x). I pasted a quick example of it shown in the attachment.

It seems it is a bad habbit not to always include the product mark when working with letters.
