What pete earned = p
What sam earned was twice p + 10 = 2p + 10
Together they made 2p+10+p which = 760
Add up the p term on the left to get 3p + 10 = 760
Subtract the constant 10 from both sides to get the p term by itself on left.
3p +10 -10 = 760 - 10
so 3p = 750
Divide both sides by 3 to get the p term solved.
3p/3 = 750/3
p = 250 dollars for Pete
2p+10 = 510 dollars for Sam

Start by removing the $10 extra and set that aside. What you have left is $750. Sam made two parts of that and Pete made one part, so you divide the $750 by three parts. 750 divided by 3 is 250. So Pete's one part is $250. Sam made twice that, or $500. And then Sam made the extra $10. TO CHECK:
$250 for Pete
$500 for Sam (twice what Pete made)
$10 extra for Sam
_____________
$760 total. No algebra is needed for this one.

p=Pete 2p+10=Sam
p+(2p+10)=760
3p+10=760
3p+10-10=760-10
3p=750
3p/3=750/3
p=250
2p+10
2(250)+10=560
So Pete earned $250 and Sam made $560

sam = 2p + 10
pete = p
2p + p + 10 = 760
subtract 10 from both sides: 2p +p = 750
combine the p's: 3p = 750
divide both sides by 3 (solve for p) p = 250
p = 250 = PETE
2p + 10 = 510 = SAM

heres how to solve it:
2x+10=760
subtract 10 from both sides and get
2x=750
divide 2 by both sides and get
x=375
so pete is $375
sam is $387

$380. They agreed the money would be for "Mardi Gras" and they split 50/50 to go pick up some girls and have some fun.
