1/2x=2/x +3

x/(x+1)=2x/(3x+3)+1

2/x -1=4/x^2 -1

5/x^2+x - 1/x^2 -x=0

5x/(3x-4)=1/(4-3x)-2

7/(x^2+x)+1/(x^2-x)=6/(x^2-1)

1/(x-2)=(1-x)/(2-x) -3

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

x/(2x-3)+5/(3-2x)=4

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

4/(x-2)-16/(x^2-4)=-3/(x+2)

80/(x+3)=60/(x-3)

1/(x-1)=2/(x^2-1)

100/x=30/(x-7)

2640/2x=2640/x -120

2/x=3/(x+1)

2x/(2x+5)+5/(5x-2)=1

x/(x-6)=(x-2)/(x-3)

(x-1)/(x-2)=1/(x-2)

1/(x^2+5x-6)=1/(x^2+x+6)
