x = number of years
14 = pam's current age
14+x = pam's future age
37 = her dad's current age
37+x = her dad's future age
We're looking to see when her dad will be exactly twice as old as she will be.
her dad's future age = 2*(pam's future age)
37+x = 2*(14+x)
37+x = 28+2x
x-2x = 28-37
-x = -9
x = 9
In 9 years, her dad will be twice her age.
Pam: 14+x = 14+9 = 23
her dad: 37+x = 37+9 = 46
46/23 = 2 shows that he will be twice her age by this point, and the answer is confirmed.

Pam is 14 and her dad is 37. In how many
years will Pam's dad be twice as old as
she will be?
Equation:
Answer:
~~~~~~~~~~~~~~~~
Equation: 2*(14+x) = 37+x. (x represents the years from now)
ANSWER. x = 37 - 2*14 = 37 - 28 = 9. In 9 years.
CHECK. In 9 years, the younger person will be 14+9 = 23 years old;
the older person will be 37+9 = 46 years old.
The ratio is then = 2. Correct.
Solved.
