Step-by-step explanation:

Solve for x :

2(  

x+3

x−1

​  

)−7(

2(  

x+3

x−1

​  

)−7(  

x−1

x+3

​  

)=5

⇒  

(x+3)(x−1)

2(x−1)  

2

−7(x+3)  

2

 

​  

=5

⇒2x  

2

+2−4x−7x  

2

−63−42x=5x  

2

+10x−15

⇒10x  

2

+56x+46=0

⇒5x  

2

+28x+23=0

⇒5x  

2

+5x+23x+23=0

⇒(x+1)(5x+23)=0

⇒x=−1 OR x=−
