Question 1126052: Hi!
I have an algebra word problem that says:
A man's age is now five ninths of what it will be in 18 years from now. How old is he now?
I started the problem and decided the equation would be x=5/9(18+x), but I never get a whole number. Could you explain this a little more in depth with me? And if your equation is different than mine, could you also explain how you got the equation?
Thank you so much!

:
I think your equation is correct
x = (x+18)
9x = 5(x+18)
9x = 5x + 90
9x - 5x = 90
4x = 90
x = 90/4
x = 22.5, not an integer
but it checks out
22.5 = (22.5+18)
22.5 = (40.5)
22.5 = 22.5
Whoever created this problem, screwed it up!
