Q. Solve for all values of x x .\newlinex5x+9=2x \frac{x-5}{x+9}=\frac{2}{x} \newlineAnswer: x= x=
  1. Find Common Denominator: First, we need to find a common denominator to combine the fractions on both sides of the equation. The common denominator here is x(x+9)x(x+9).
  2. Multiply by Common Denominator: Next, we multiply both sides of the equation by the common denominator to eliminate the fractions: x(x+9)×(x5)(x+9)=x(x+9)×2xx(x+9) \times \frac{(x-5)}{(x+9)} = x(x+9) \times \frac{2}{x}
  3. Simplify Equation: Simplify the equation by canceling out the common terms on both sides:\newlinex(x5)=2(x+9)x(x-5) = 2(x+9)
  4. Distribute and Combine Terms: Now, distribute the xx on the left side and the 22 on the right side: x25x=2x+18x^2 - 5x = 2x + 18
  5. Set Equation to Zero: Bring all terms to one side to set the equation to zero and combine like terms:\newlinex25x2x18=0x^2 - 5x - 2x - 18 = 0\newlinex27x18=0x^2 - 7x - 18 = 0
  6. Factor Quadratic Equation: Factor the quadratic equation: \newline(x9)(x+2)=0(x - 9)(x + 2) = 0
  7. Solve for x: Set each factor equal to zero and solve for x:\newlinex9=0x - 9 = 0 or x+2=0x + 2 = 0\newlinex=9x = 9 or x=2x = -2
  8. Check Solutions: We must check these solutions to ensure they do not make the original equation undefined by causing division by zero. The original equation has xx in the denominator, so xx cannot be 00. Also, xx cannot be 9-9 because that would make the denominator of the left side of the original equation zero.
  9. Check x=9x = 9: Checking x=9x = 9:
    959+9=29\frac{9-5}{9+9} = \frac{2}{9}
    418=29\frac{4}{18} = \frac{2}{9}
    29=29\frac{2}{9} = \frac{2}{9} (This is true, so x=9x = 9 is a valid solution.)
  10. Check x=2x = -2: Checking x=2x = -2:
    252+9=22\frac{-2-5}{-2+9} = \frac{2}{-2}
    7/7=1-7/7 = -1
    1=1-1 = -1 (This is true, but we must remember that xx cannot be 2-2 because it would make the original right side of the equation undefined.)
  11. Discard Invalid Solution: Since x=2x = -2 makes the original equation undefined, we discard this solution. The only solution is x=9x = 9.
