Let x be Deborah's age, in years.
Therefore her father's age is 2x.
Their ages add up to 45:
x + 2x = 45
Solve for x.
If you haven't learned to use variables and equations yet, you can set up a table with these headers:
Deb's age.....dad's age....adds to 45?
And start systematically trying numbers.

45/2= 22.5 So she is 22 an a half years old.
