Let f (x) be a continuous even function defined in R, and if x > 0, f (x) is a monotone function, then the sum of all x satisfying f (x) = (x + 3 / x + 4) is
When x > 0, f (x) is a monotone function
And f (- x) = f (x)
So: when x

If you think about it this way, you've confused what the topic asks for
It is true that f (- x) = f [(x + 3) / (x + 4)], but it can only guarantee that the left part of F (x) = f [(x + 3) / (x + 4)] remains unchanged, and the right part can not be guaranteed, because (- x + 3) / (- x + 4) is not necessarily equal to X or - X. The X in F (x) = f [(x + 3) / (x + 4)] is the same X, you change the left X and the right X. if you think about f [(x + 3) / (x + 4)] = f [(x + 1) / (x + 2)], you change x into - X, Maybe the values on both sides will change. The X in the title should be specific to the x it gives, which is the X in (x + 3) / (x + 4), not taking (x + 3) / (x + 4) as a whole
In fact, you have already considered the situation in the process of solving. According to that classification, there are only two situations. If you want to use f (- x) = f (x), you must "negative" all of F, for example, (x + 3) / (x + 4) "negative" is - [(x + 3) / (x + 4)]

A mathematical problem Olympic x = Olympic

Suppose that Sai is equal to 4, Ao can only be an even number 2, gram can only be equal to 8, then let Lin = x, pi = y, then there is 4 (10x + y) + 3 = 10Y + X, simplify to 13y-2x + 1 = 0, easily solve to x = 7, y = 1. So it is 2178 * 4 = 8712
To sum up, it can only be 2178 * 4 = 8712

1.2.3.4.5.6.7.8.9. Equal to 14, can only use addition and subtraction, how to calculate

It's impossible
1 + 2 + 3 + --- + 9 = 45 is an odd number, so no matter what plus sign in the middle becomes a minus sign (one plus one minus, that's two times, so it's even), odd even = odd. It can't be equal to 14
So there is no solution to this problem
