Hi.
Usually, solve(f(x),x) returns noun form of expression f(x) if it can't
solve.
For example:
solve(sin(x)=log(x),x); ==> [sin(x) = log(x)]
I know that 'solve' function can not solve equations with absolute
functions. It can do to_poly_solve().
Strange behavior of 'solve':
solve(log(abs(35*x+1))=0,x); ==>[] (instead of
[log(abs(35*x+1))=0])
But if "simp:false" then solve(log(abs(35*x+1))=0,x) returns noun form of
input.
