Fifteen years ago a man was two-thirds as old as he will be in 12 years.
How old is he now? It's x
:
x - 15 = (x+12)
:
Multiply both sides by 3 to get rid of the annoying demominator
3(x-15) = 3*(x+12)
:
3x - 45 = 2(x+12)
:
3x - 45 = 2x + 24
:
3x - 2x = 24 + 45
:
x = 69 yrs now, an old guy like me!

Check solution in the statement:
"Fifteen years ago a man was two-thirds as old as he will be in 12 years."
69 - 15 = (69 + 12)
54 = *81
54 = 54
