The product of two positive numbers is 1,800. one number is twice the other number. the equation to determine the two numbers, with x representing the value of the lesser number, is x(2x) = 1,800.

what is the value of the lesser number?

24
30
48
60

It is e) i am not sure if you have any questions or need any

Ithink it is 52

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.
