**Reiny**, Monday, December 3, 2012 at 11:01amEmma's present age ---- x

son's present age -------y

in 5 years:

Emma = x+5

Son = y+5

but x+5 = 2(y+5) +3

x - 2y = 8 (#1)

5 years ago:

Emma = x-5

Son = y-5

x-5 = 5(y-5) - 2

x-5 = 5y - 25 - 2

x - 5y = -22 (#2)

#1 - #2:

3y = 30

y = 10

in #1 : x -20 = 8

x = 28

Emma now is 28, her son is now 10

check:

in 5 from now:

>b> Emma is 33 , her son is 15

is 33 three more than twice 15 ? YES

5 years ago:

Emma was 23 , her son was 5

is 23 two less than 5 times 5 ? YES

All is good
