Answer: 60
Lets make the people into variables first
Ted = x
Rosie = y
The sum of their ages is 72 so
x + y = 72
Ted is 5 times as old as rosie was when ted was Rosie's age
x = 5y
Now lets put in 5y instead of x so we can solve for y
5y + y = 72
6y = 72
y = 12
If y = 12 then we can put that in to get ted's age
x = 5(12)
x = 60
Ted is 60!
Lets check our work,
since we know the sum is 72 we can add their ages to check,
60 + 12 = 72
Yep! This is right.
Hope this helped! If you could mark branliest i'd appreciate it a lot. Let me know if you need anything else!
