Solve[some equations, x] y=x*5/.% -----Original Message----- From: Tim Heger [mailto:timheger at yahoo.com] Sent: Saturday, January 31, 2009 7:12 AM To: mathgroup at smc.vnet.net Subject: [mg96004] [mg95963] NEWBIE: How do I use the results of a Solve? I can't figure out how to use the results of Solve I just created as a new variable. Here's a simple example of what I am trying to do: Solve[some equation, x] Results in {x->12} I then want to use the x in y = x * 5 for example.... Obviously when I try to use this it fails because Mathematica sees the equation as y = {x->12} * 5 and not y = 12 *5 ... How do I change the results from the Solve from a rule to an actual value I can then use? Thanks, Tim
