When 1 / 2 * (1000 / 435 + X / 1000) - 1 = 0.05/0.15/0.25/0.35, the values of X are respectively? Note: X is rounded | Math enthusiast | Mathematical art

When 1 / 2 * (1000 / 435 + X / 1000) - 1 = 0.05/0.15/0.25/0.35, the values of X are respectively? Note: X is rounded

1/2*（1000/435+X/1000）-1=t
X=[2(t+1)-1000/435]*1000
When t = 0.05, 0.15, 0.25 and 0.35, the values can be obtained respectively
X = - 198.85,1.15201.15401.15, which can be obtained by rounding
X=-198,1,201,401

12. If we know x + y = 5, then x + y + 6 = 5 + 6 = 11; if we know x + y + 6 = 15, then x + y = 5, the above operations reflect the overall idea, we can regard x + y as Given a + B = a, ab = a + 2011, 1-2 (a + AB) + (ab-2b) = 3A, you can determine the value of a + B and AB, if you can find the value
13. If x + y = 5 is known, then x + y + 6 = 5 + 6 = 11; if x + y + 6 = 15 is known, then x + y = 9.
