I just watched someone solve this problem and I don't understand how this person got the answer that she got.
Hello Amie,
If we call the number of years we are looking forward x, then we can state the problem this way:
Julio's age plus some number of years is double James' age plus the same number of years.
or
36+x=2(11+x)
Then we just have to solve for x.
36+x=2(11+x)
36+x=22+2x distribute
14+x=2x subtract 22 from each side
14=x subtract x from each side
We have that x is 14 years. This makes sense because in 14 year, Julio will be 50 and James will be 25.
