x+5+x-3/(x-3)(x+5)=1/3
=》2x+2/x^2+2x-15=1/3
=》x^2+2x-15=6x+6
=》x^2-4x-21=0
=》x^2-7x+3x-21=0
=》x(x-7)+3 (x-7)=0
=》(x-7)(x+3)=0
=》x-7=0 or x+3=0
=》x=7 or x = -3 ( it is not possible)
hence the value of x is 7

The answer is x=7 .
The solution is in the photo . Although 'x' has two values : 7 and -3 but after putting each of the values and testing the answers , the value of 'x' is 7.
