Option A:
(10)/(9) is the solution of x

Step-by-step explanation:

The given expression is
(7)/((x+2))+(11)/((x-5))=(7)/((x+2)(x-5))

We need to determine the value of x.

The value of x can be determined by solving the expression for x.

Taking LCM , we get,


(7(x-5)+11(x+2))/((x+2)(x-5))=(7)/((x+2)(x-5))

Since, the denominator is common for both sides of the equation, let us cancel the denominator.

Thus, we have,


7(x-5)+11(x+2)=7

Multiplying the terms within the bracket, we get,


7x-35+11x+22=7

Adding the like terms, we get,


18x-13=7

Adding both sides of the equation by 13, we have,


18x=20

Dividing both sides of the equation by 18,


x=(20)/(18)

Simplifying, we get,


x=(10)/(9)

Thus, the solution is
(10)/(9)

Therefore, Option A is the correct answer.
