The correct Answer is:
To solve the equation \[ \frac{24x^2 + 25x - 47}{ax - 2} = -8x - 3 - \frac{53}{ax - 2} \] we will follow these steps: ### Step 1: Combine the Right-Hand Side (RHS) The RHS has two fractions. To combine them, we need a common denominator, which is \( ax - 2 \). \[ -8x - 3 - \frac{53}{ax - 2} = \frac{(-8x - 3)(ax - 2) - 53}{ax - 2} \] ### Step 2: Expand the Numerator on the RHS Now we will expand the numerator: \[ (-8x - 3)(ax - 2) = -8ax^2 + 16x - 3ax + 6 \] So, the RHS becomes: \[ \frac{-8ax^2 + (16 - 3a)x + 6 - 53}{ax - 2} = \frac{-8ax^2 + (16 - 3a)x - 47}{ax - 2} \] ### Step 3: Set the Numerators Equal Since the denominators are the same, we can set the numerators equal to each other: \[ 24x^2 + 25x - 47 = -8ax^2 + (16 - 3a)x - 47 \] ### Step 4: Compare Coefficients Now we will compare the coefficients of \( x^2 \) and \( x \): 1. For \( x^2 \): \[ 24 = -8a \] 2. For \( x \): \[ 25 = 16 - 3a \] ### Step 5: Solve for \( a \) From the first equation: \[ a = \frac{24}{-8} = -3 \] Now, let's verify using the second equation: Substituting \( a = -3 \): \[ 25 = 16 - 3(-3) \implies 25 = 16 + 9 \implies 25 = 25 \] Both equations are satisfied. ### Conclusion The value of \( a \) is \[ \boxed{-3} \]
