Step-by-step solution

To solve this problem, follow these steps:

  • Step 1: Cross-multiply to eliminate the fractions.
  • Step 2: Solve the resulting linear equation.

Let's proceed step-by-step:

Step 1: Given the equation 9x+5=112x \frac{9}{x+5} = \frac{11}{2-x} , we will cross-multiply:

9×(2x)=11×(x+5) 9 \times (2 - x) = 11 \times (x + 5)

Simplify both sides:

189x=11x+55 18 - 9x = 11x + 55

Step 2: Solve for x x .

First, rearrange the terms to get all terms involving x x on one side:

1855=11x+9x 18 - 55 = 11x + 9x

37=20x -37 = 20x

Divide both sides by 20 to solve for x x :

x=3720 x = -\frac{37}{20}

Thus, the solution to the problem is x=3720 x = -\frac{37}{20} .

Final Answer

3720 -\frac{37}{20}
