<PRE><B>Question 214165</B>
a = your age now
;
40 years ago i was 1/3 the age i will be in 4 years.
a - 40 = {{{1/3}}}(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 = {{{1/3}}}(62 + 4)
22 = {{{1/3}}}(66)
