sven is thinking of two numbers. the sum is 12. the diffrence is 4. what are the two numbers?
4 & 8
I hope Sven didn't have to think too hard about that. There aren't too many numbers less than 12. :-)
Sum 12 diffrence 4
To find the two numbers that Sven is thinking of, we can set up a system of equations based on the given information.
Let's represent the two numbers as x and y.
1. The sum of the two numbers is 12:
x + y = 12
2. The difference between the two numbers is 4:
x - y = 4
Now we have a system of two equations with two variables. We can solve this system of equations to find the values of x and y.
There are different methods to solve a system of equations, such as substitution, elimination, or using a matrix. Let's use the elimination method in this case:
1. Add the two equations together:
(x + y) + (x - y) = 12 + 4
Simplify the equation:
2x = 16
2. Divide both sides of the equation by 2 to isolate x:
x = 8
3. Substitute the value of x back into one of the original equations (let's use the first equation):
8 + y = 12
4. Solve for y:
y = 12 - 8
y = 4
Therefore, the two numbers Sven is thinking of are 8 and 4.
