Homework Help: precalc

Posted by eragon on Saturday, January 13, 2007 at 5:57pm.

I'm terrible at pre calc, could someone tell me if the solution set for log subscript 2 x + log sub 2 (x-1)=1 is the solution -1? Using either the elimination or substitution method is the solution set for 4x + y =11 and 2x -y = 7 is the answer (3, -1)? Kudos!

Yes.
