Solve the equation x + 1 / X-1 + 1-2x / 2x = 0

Solve the equation x + 1 / X-1 + 1-2x / 2x = 0

(x-1)/(x+1)+2x/(1-2x)=0
(x-1)(1-2x)+2x(x+1)=0
-2x^2+3x-1+2x^2+2x=0
5x=1
x=1/5

1. We know that {x + y = 5, y + Z = - 2, Z + x = 3, find the value of X + y + Z. 2. The solutions of the system of linear equations {3x + 2Y = m + 32x-y = 2m-1 are opposite to each other,
1. It is known that {x + y = 5
Y+z=-2
Z + x = 3 find the value of X + y + Z
2. Binary linear equations {3x + 2Y = m + 3
The solutions of 2x - y = 2m - 1 are opposite to each other, and the value of M is obtained

1、x+y+z=3
2、m=-10

The solution of the equations {2x + 3My = 21,4x + y = 17 is the solution of the binary linear equation 2x-y = 1

4x+y=17
2x-y=1
Add: 6x = 18
x=3
Substituting, y = 5, M = 1
