You need two equals like == not one. You need brackets also and not
parenthesis. Then it works. There are 4 roots by the way. Looks like you
only want the real ones.

Solve[x^4-1==3,x]

I have tried multiple problems (simple ones albiet) to solve while in
ALG mode.
SOLVE(x^4 - 1 = 3, x)
but this provides no result. Just returns the question with no answer.
The answer should be x = -Sqrt(2) or x = sqrt(2).

The example works in RPN, but I use both environments depending what I
am doing. It worked before the upgrade. 
Am I missing something here!
