First, multiply the whole thing by 10. You get
P+21=46P-19+5P
Gather like terms
P+21=51P-19
Subtract P from both sides
21=50P-19
add 19 to both sides
40=50P
devide b.s by 40
4/5=P
ie P = .8

You know, I don't mind helping people who truly need help, but it seems to me, if you actually took some of the tips people have given you, and actually sat down and worked on some of these problems, you'd probably be done by now.
