The correct Answer is:
To solve the equation \(\frac{x + 3}{x + 2} = \frac{3x - 7}{2x - 3}\), we will use cross multiplication. Here are the steps: ### Step 1: Cross Multiply Cross multiplying gives us: \[ (x + 3)(2x - 3) = (x + 2)(3x - 7) \] ### Step 2: Expand Both Sides Now, we will expand both sides of the equation. - Left side: \[ x(2x) + x(-3) + 3(2x) + 3(-3) = 2x^2 - 3x + 6x - 9 = 2x^2 + 3x - 9 \] - Right side: \[ x(3x) + x(-7) + 2(3x) + 2(-7) = 3x^2 - 7x + 6x - 14 = 3x^2 - x - 14 \] ### Step 3: Set the Equation to Zero Now, we set the equation to zero by moving all terms to one side: \[ 2x^2 + 3x - 9 - (3x^2 - x - 14) = 0 \] This simplifies to: \[ 2x^2 + 3x - 9 - 3x^2 + x + 14 = 0 \] Combining like terms gives: \[ - x^2 + 4x + 5 = 0 \] or \[ x^2 - 4x - 5 = 0 \quad \text{(Multiplying through by -1)} \] ### Step 4: Factor the Quadratic Equation Next, we factor the quadratic equation: \[ (x - 5)(x + 1) = 0 \] ### Step 5: Solve for x Setting each factor to zero gives us the solutions: \[ x - 5 = 0 \quad \Rightarrow \quad x = 5 \] \[ x + 1 = 0 \quad \Rightarrow \quad x = -1 \] ### Step 6: Check for Extraneous Solutions We need to check if our solutions are valid given the restrictions \(x \neq 2\) and \(x \neq \frac{3}{2}\): - \(x = 5\) is valid. - \(x = -1\) is also valid. ### Final Answer The solutions to the equation are: \[ x = 5 \quad \text{and} \quad x = -1 \] ---
