Phil has three times as many DVDS as sam has. Even after Phil gives Sam 6 DVDs, he still has 16 more DVDs than Sam has. What was the original number of DVDs that Phil had?
I set this up like so,
P=3*S
P-6=16+S+6
(S=Sam)
How do I solve this? Any answers appreciated!
I can finish that, to end up getting 14=s. Thank you very much! What a simple blunder-_- All that frustration for nothing! My SAT book gave this strategy, which threw me off.
P=3S P/3=S
P-6=16+P/3+6
P-6=48+P+18/3
3P-18=48+P+18
2P=84
P=42.
^^The book (Grubers 2013) Is trying to say that this is a simpler strategy. I disagree. Thanks for the wonderful help!
