Deborah's father is twice as old she is now.if their ages add up to 45 years how old is Deborah.

Answer 1

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.

Answer 2

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