if you add Fred's age to 4 times Natalie's age, the result is 76

How old is Fred
How old is Natalie​

Answer 1

Answer:

24, 13

Step-by-step explanation:

n + f = 37, so f = 37 - n

f + 4n = 76  now substitute the first equation into the second

37 - n + 4n = 76

37 + 3n = 76

3n = 39

n = 13  Natalie is 13

n + f = 37, so 13 + f = 37, so Fred is 24
