    Let's call the first number "x" and the second number "y". From the problem, we know two things:

    1. x + y = 10 (the sum of the two numbers is 10)
    2. x + 2y = 8 (if you add the first number to twice the second number, the result is 8)

    We can use algebra to solve for x and y. Here's one way to do it:

    1. Solve the first equation for x: x = 10 - y
    2. Substitute x in the second equation with 10 - y: 10 - y + 2y = 8
    3. Simplify the equation: 10 + y = 8
    4. Solve for y: y = -2
    5. Use the value of y to solve for x using the first equation: x + (-2) = 10, so x = 12

    Therefore, the two numbers are 12 and -2.

    Note: It's always a good idea to check your answer to make sure it makes sense in the context of the problem. In this case, we can see that 12 + (-2) does indeed equal 10, and that 12 + 2(-2) equals 8. So we can be confident that our solution is correct.
