the sum of two numbers is 9 and their difference is 3. what are the two numbers?

Answer 1

Let's call the two numbers x and y.

According to the information given:
x + y = 9
x - y = 3

We can solve these two equations simultaneously to find the values of x and y.

Adding the two equations together, we get:
2x = 12
x = 6

Substitute x = 6 back into the first equation to solve for y:
6 + y = 9
y = 3

Therefore, the two numbers are 6 and 3.
