Hi there! Natalie's age is 13 and Fred's age is 26
Let 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 = 39
The 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
Let Natalie's age be represented by x.
