Question 1201635
<font color=black size=3>
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.


Equation: 37+x = 2(14+x)
Answer: 9 years
