Final answer:
By solving a system of linear equations, Jana is determined to be 29 years old and Tony is 4 years old.
Step-by-step explanation:
The question involves solving a system of linear equations to find the ages of Jana and Tony. Let's denote Tony's age as T and Jana's age as J. From the problem, we have two equations: J = T + 25 and J + T = 33. We can substitute the first equation into the second to find T.
- J = T + 25
- J + T = 33
- (T + 25) + T = 33
- 2T + 25 = 33
- 2T = 33 - 25
- 2T = 8
- T = 4
Now we know Tony is 4 years old. To find Jana's age, we use the first equation:
- J = T + 25
- J = 4 + 25
- J = 29
Therefore, Jana is 29 years old.
