Question from May, a student: The sum of two numbers is 36. |
Hi May,
You don't know either number so give them names. Call the first number x and the second number y. Since the sum of the two numbers is 36 you know that
x + y = 36.
From this I can see that I don't need names for each number since if one number is x the other is 36 - x.
Now you know that the product of the two numbers is 320 so
x × (36 - x) = 320
Can you solve this for x?
