Hi there! Natalie's age is
13 and Fred's age is
26Let Natalie's age be represented by
x.Let Fred's age be represented by
y.The sum of Natalie's and Fred's age is 39, so
x + y = 39The sum of three times Natalie's and (one time) Fred's age is 65, so
3x + y = 65

Eliminate y by subtracting


Divide by -2



Subract 13

Therefore, Natalie's age is
13 and Fred's age is
26
