Emma'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
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
