The correct Answer is:
To solve the equation \(\frac{2x}{3} - \frac{3x}{8} = \frac{7}{12}\), we will follow these steps: ### Step 1: Find the Least Common Multiple (LCM) First, we need to find the LCM of the denominators 3, 8, and 12. - The LCM of 3 and 8 is 24. - The LCM of 24 and 12 is still 24. ### Step 2: Rewrite the Equation Now, we will rewrite each term with the common denominator of 24: \[ \frac{2x}{3} = \frac{2x \cdot 8}{3 \cdot 8} = \frac{16x}{24} \] \[ \frac{3x}{8} = \frac{3x \cdot 3}{8 \cdot 3} = \frac{9x}{24} \] \[ \frac{7}{12} = \frac{7 \cdot 2}{12 \cdot 2} = \frac{14}{24} \] So, the equation becomes: \[ \frac{16x}{24} - \frac{9x}{24} = \frac{14}{24} \] ### Step 3: Combine the Left Side Now, we can combine the left side of the equation: \[ \frac{16x - 9x}{24} = \frac{14}{24} \] This simplifies to: \[ \frac{7x}{24} = \frac{14}{24} \] ### Step 4: Eliminate the Denominator To eliminate the denominator, we can multiply both sides of the equation by 24: \[ 7x = 14 \] ### Step 5: Solve for \(x\) Now, divide both sides by 7: \[ x = \frac{14}{7} \] This simplifies to: \[ x = 2 \] ### Final Answer Thus, the solution to the equation is: \[ \boxed{2} \]
