Final answer:
The sum of two numbers is 12 and their difference is 4. The two numbers are 8 and 4.
Step-by-step explanation:
Let's call the two numbers x and y. We are given that the sum of the numbers is 12, so we can write the equation x + y = 12. We are also given that their difference is 4, so we can write the equation x - y = 4. We can solve these two equations to find the values of x and y.
- Add the two equations together: (x + y) + (x - y) = 12 + 4.
- Combine like terms: 2x = 16.
- Divide both sides of the equation by 2 to solve for x: x = 8.
- Substitute the value of x back into one of the original equations to solve for y: 8 + y = 12.
- Solve for y: y = 4.
So, the two numbers are 8 and 4.
