50-2x equals 3x + 20 to solve the equation

50-2x equals 3x + 20 to solve the equation

The solution equation: 20% x + 30% x = 2.5; x-14x = 60; 50-3x = 20

（1）20%X+30%X=2.5             50%X=2.5        50%X÷50%=2.5÷50%      ...

Solving the equation 2x-1 / 3x 1 = 2x-5 / 3x-1

(2x-1)% (3x + 1) = (2x-5)% (3x-1)
(3x+1)(2x-5)=(3x-1)(2x-1)
6x^2-13x-5=6x^2-5x+1
-13x+5x=1+5
-8x=6
x=-3/4

Solution equation: 2x + 1 / x-3x / 2x + 1 = 2
I will hand in my homework at two o'clock this afternoon,

(2x+1)/x-3x/(2x+1)=2
(2x+1)^2-3x^2=2x(2x+1)
(2x+1)^2-2x(2x+1)-3x^2=0
(2x+1-3x)(2x+1+x)=0
(1-x)(3x+1)=0
x1=1 x2=-1/3
