two junked cars were sold at auction to a buyer who paid a total of $2,000 for both cars. If the more expensive of the two cars was $240 less than three times the price of the cheaper car, how much was the more expensive car?
how do I solve this word problem?

X + Y = 2000
X = 3Y240
3Y240 + Y = 2000
4Y  240 = 2000
4Y = 2240
Y = 560
X = 1440 
the amount of money earned on a job is diretly proportional to the number of hours worked. if $76 is earned for h of work, how much is earned for 34 h of work.
