Solve the equation \( \frac{8}{x-9}+\frac{x}{x+5}=\frac{-13x+13}{x^{2}-4x-45} \). Solve the equation by following steps: - step0: Solve for \(x\): \(\frac{8}{x-9}+\frac{x}{x+5}=\frac{-13x+13}{x^{2}-4x-45}\) - step1: Find the domain: \(\frac{8}{x-9}+\frac{x}{x+5}=\frac{-13x+13}{x^{2}-4x-45},x \in \left(-\infty,-5\right)\cup \left(-5,9\right)\cup \left(9,+\infty\right)\) - step2: Multiply both sides of the equation by LCD: \(\left(\frac{8}{x-9}+\frac{x}{x+5}\right)\left(x-9\right)\left(x+5\right)=\frac{-13x+13}{x^{2}-4x-45}\times \left(x-9\right)\left(x+5\right)\) - step3: Simplify the equation: \(-x+40+x^{2}=-13x+13\) - step4: Move the expression to the left side: \(-x+40+x^{2}-\left(-13x+13\right)=0\) - step5: Calculate: \(12x+27+x^{2}=0\) - step6: Factor the expression: \(\left(3+x\right)\left(9+x\right)=0\) - step7: Separate into possible cases: \(\begin{align}&3+x=0\\&9+x=0\end{align}\) - step8: Solve the equation: \(\begin{align}&x=-3\\&x=-9\end{align}\) - step9: Check if the solution is in the defined range: \(\begin{align}&x=-3\\&x=-9\end{align},x \in \left(-\infty,-5\right)\cup \left(-5,9\right)\cup \left(9,+\infty\right)\) - step10: Find the intersection: \(\begin{align}&x=-3\\&x=-9\end{align}\) - step11: Rewrite: \(x_{1}=-9,x_{2}=-3\) The solutions to the equation \( \frac{8}{x-9}+\frac{x}{x+5}=\frac{-13x+13}{x^{2}-4x-45} \) are \( x=-9 \) and \( x=-3 \).

To solve the equation \( \frac{8}{x-9}+\frac{x}{x+5}=\frac{-13 x+13}{x^{2}-4 x-45} \), first, you can simplify the right side. Notice that \( x^2 - 4x - 45 \) factors to \( (x - 9)(x + 5) \). This gives us the equation \( \frac{8}{x-9} + \frac{x}{x+5} = \frac{-13x+13}{(x-9)(x+5)} \). Next, you can multiply through by \((x - 9)(x + 5)\) to eliminate the denominators. After distributing and collecting like terms, you’ll get a polynomial equation to solve for \( x \). Don’t forget to check for extraneous solutions! In terms of real-world applications, equations like this one can arise in fields such as physics when dealing with rates and motion, or in finance when calculating profit or loss based on varying conditions. Understanding how to manipulate and solve these equations can help in making informed decisions in real-life scenarios!
