let L = Lindy's age
then ben's age is L+2
and L + L+2 = 40 at most
or 2L +2 = 40
or 2L = 38
or L = 19 = Lindy's age
and then 19 +2 = 21 = Ben's age

B = l +2
l + 2 + l = 40
2l + 2 = 40
2l = 38
l = 38/2 = 19
hence B = 19+2= 21

b = l + 2
l + b <= 40
l + (l + 2) <= 40
l + l + 2 <= 40
2l + 2 <= 40
2l <= 38
l <= 19
At most she is 19 years old
