When x______ The value of formula 3x-5 is greater than that of formula 5x + 3

When x______ The value of formula 3x-5 is greater than that of formula 5x + 3

If the inequality 3x-5 ＞ 5x + 3 is obtained by shifting the term first, 3x-5x ＞ 3 + 5 is obtained by combining the similar terms, - 2x ＞ 8 is obtained, that is, X ＜ - 4

How to solve an equation with two XS? For example: 3x-0.5x = 5

3X-0.5X=5
Because 3x and 0.5x are of the same kind
So put the coefficients in front of 3x-0.5x together
That is, (3-0.5) x = 5
Because 3-0.5 = 2.5
So 2.5x = 5
And then divide X by X, and you have to
x=2

It is known that the image of function f (x) = 1 + 3x / 1-2x and function g (x) is symmetric with respect to the line y = X
Given that the image of the function f (x) = (1 + 3x) / (1-2x) and the function g (x) is symmetric with respect to the line y = x, and that the function H (x) and the function g (x + 2) are reciprocal functions, the solution of H (4)

The solution is symmetric by the image of function f (x) = (1 + 3x) / (1-2x) and function g (x) with respect to the line y = X
We know that the function f (x) = (1 + 3x) / (1-2x) and the function g (x) are reciprocal functions,
That is, y = f (x) = (1 + 3x) / (1-2x)
That is y-2xy = 1 + 3x
That is 3x + 2XY = Y-1
That is, x = (Y-1) / (3 + 2Y)
So g (x) = (x-1) / (3 + 2x)
So g (x + 2) = (x + 1) / (7 + 2x)
Let H (4) = a
The function H (x) and function g (x + 2) are reciprocal functions,
Let g (a) = 4
That is, (a + 1) / (7 + 2a) = 4
That is a + 1 = 28 + 8A
That is, 7a = - 27
That is a = - 27 / 7
So h (4) = - 27 / 7
