Milton needs to find the product of two numbers. one of the number is 6. the answer also needs to be 6 how will you solve this problem?

Any number multiplied by one is equal to itself.  Therefore, six multiplied by one will be equal to six.  As a result, one is the answer.

Can you tell us the question

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
