# Tom is 3 times as old as jerry, in 10 years he will be twice as old as jerry will be then, how old are the boys now?

Tom is

You were given two pieces of information, one about the relationship between the current ages of the boys, and the other about the relationship between their ages 10 years from now.

So, you know that at this point in time, Tom is three times older than Jerry. This means that you can write

This means that you can write

This will be your system of equations

Let's denote Tom's current age as T and Jerry's current age as J. According to the information given:

- T = 3J
- T + 10 = 2(J + 10)

Now, we can solve these equations simultaneously:

- Substitute T = 3J into equation 2: 3J + 10 = 2(J + 10)
- Expand and solve for J: 3J + 10 = 2J + 20 J = 10

Now that we have Jerry's current age, we can find Tom's age using the first equation: T = 3 * 10 T = 30

So, Tom is 30 years old and Jerry is 10 years old.
