The polynomials 0.108x²-0.876x+474.1 and 0.047x²+9.694x+361.7 approximate the number of bachelor's degrees, in thousands, earned by males and females, respectively, where x is the number of years after 1971. Find the polynomial that represents the difference between bachelor's degrees earned by both men and women. (Subtract, use parenthesis!) *​

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.
