How did you get your answer?
It is not correct
Felicia's present age .... f
Tom's present age ........ t
3f = t+4 **
f+3 + t+3 = 30
f+t = 24
t = 24 - f ***
sub *** into **
3f = 24-f + 4
4f = 28
f = 7
then t = 24-7 =17
Felicia is now 7 and Tom is now 17
check:
three times Felicia's age is 21, which is 4 more than Tom's age
in three years from now:
Felicia is 10 and Tom is 20, with a sum of 30
