a = your age now

40 years ago i was 1/3 the age i will be in 4 years.
a - 40 = 1%2F3(a+4)
Multiply both sides by 3, to get rid of the annoying fraction
3a - 120 = a + 4
3a - a = 4 + 120
2a = 124
a = 62 yr is your age now

Check in the statement:
40 years ago i was 1/3 the age i will be in 4 years.
62 - 40 = 1%2F3(62 + 4)
22 = 1%2F3(66)

Let a = your current age
40 years ago, your age was a+-+40
In 4 years your age will be a+%2B+4
---------------------------------------
given:
a+-+40+=+%281%2F3%29%2A%28a+%2B+4%29
3%2A%28a+-+40%29+=+a+%2B+4
3a+-+120+=+a+%2B+4
2a+=+124
a+=+62
Your age now is 62
check:
40 years ago you were 22
In 4 years you will be 66
one third of 66 is 22
OK
