Answer 3

Let's assume the two numbers are x and y.

According to the given information:

1. The sum of the two numbers is 57: x + y = 57
2. One number is smaller than the other by 2 times: y = 2x

To find the values of x and y, we can use substitution or elimination. Let's use substitution.

Substitute the value of y from the second equation into the first equation:

x + (2x) = 57

Now, combine like terms:

3x = 57

Now, divide both sides by 3 to solve for x:

x = 57 / 3 x = 19

Now that we have the value of x, we can find the value of y using the second equation:

y = 2x y = 2 * 19 y = 38

So the two numbers are 19 and 38.
