Question 700986
Let A = your age now
Three years from now (A + 3) you will be 3 times as old as 27 years ago (A-27)
In equation form this is A+3 = 3(A-27) 
Solve for A:
A + 3 = 3A - 81
2A = 84
A = 42
So you are 42 years old
Check: 27 years ago you were 42 - 27 = 15.  Three years from now, you will be 45, which is 3x15
