Actually, no I didn't. You might want to check your solutions in the
original equations.

I'd suggest the Schaum's Outlines series. I don't know their algebra
and trigonometry books specifically, but in general they cover their
subjects thoroughly, including topics often omitted from course work.
They have lots of solved problems and lots of practice problems with
just answers, which are terrific for self study.
When I was a lad, we had College Algebra, Trigonometry, and Analytic
Geometry. Those got subsumed into Precalculus, with a lot of stuff
like matrices and theory of equations left out. I don't know whether
you'll find a Schaum's on Precalculus, or whether they still make
books on the separate topics. If you have a choice of both, you can
decide how comprehensive you want to be.
