I am having trouble with a word problem that was on a worksheet for solving systems using graphing. Here is the problem:
Five years from now, a father's age will be three times his son's age, and 5 years ago, he was seven times as old as his son was. What are their present ages?
I don't think I am doing this right, but this is what I did:
y=3x + 5
y=7x - 5
I then graphed the equations, and got the solution as (1,2). From here, I am stuck.
Thanks for the help!
