The correct Answer is:
To solve the equation \( x + 7 - \frac{8x}{3} = \frac{17x}{6} - \frac{5x}{8} \), we will follow these steps: ### Step 1: Move all terms involving \( x \) to the left side and constant terms to the right side. Starting with the equation: \[ x + 7 - \frac{8x}{3} = \frac{17x}{6} - \frac{5x}{8} \] We can rearrange it as: \[ x - \frac{8x}{3} - \frac{17x}{6} + \frac{5x}{8} = -7 \] ### Step 2: Find a common denominator for the fractions. The denominators are 3, 6, and 8. The least common multiple (LCM) of these numbers is 24. We will express each term with a denominator of 24: - \( x = \frac{24x}{24} \) - \( -\frac{8x}{3} = -\frac{64x}{24} \) (since \( 8 \times 8 = 64 \)) - \( -\frac{17x}{6} = -\frac{68x}{24} \) (since \( 17 \times 4 = 68 \)) - \( \frac{5x}{8} = \frac{15x}{24} \) (since \( 5 \times 3 = 15 \)) Now substituting these back into the equation gives: \[ \frac{24x}{24} - \frac{64x}{24} - \frac{68x}{24} + \frac{15x}{24} = -7 \] ### Step 3: Combine the terms on the left side. Combining the \( x \) terms: \[ \frac{24x - 64x - 68x + 15x}{24} = -7 \] Calculating the numerator: \[ 24 - 64 - 68 + 15 = -93 \] So we have: \[ \frac{-93x}{24} = -7 \] ### Step 4: Eliminate the fraction by multiplying both sides by 24. \[ -93x = -7 \times 24 \] Calculating the right side: \[ -7 \times 24 = -168 \] So we get: \[ -93x = -168 \] ### Step 5: Solve for \( x \). Dividing both sides by -93: \[ x = \frac{-168}{-93} = \frac{168}{93} \] ### Step 6: Simplify the fraction. To simplify \( \frac{168}{93} \), we can divide both the numerator and denominator by their greatest common divisor (GCD), which is 3: \[ x = \frac{168 \div 3}{93 \div 3} = \frac{56}{31} \] ### Final Answer: \[ x = \frac{56}{31} \] ---
