The correct Answer is:
To solve the equation \((3x-3)/4 - (2x-1)/3 = 1\), we will follow these steps: ### Step 1: Identify the equation We start with the equation: \[ \frac{3x - 3}{4} - \frac{2x - 1}{3} = 1 \] ### Step 2: Find the Least Common Multiple (LCM) The denominators are 4 and 3. The LCM of 4 and 3 is 12. ### Step 3: Rewrite the equation with the LCM We will multiply each term by the LCM (12) to eliminate the fractions: \[ 12 \cdot \left(\frac{3x - 3}{4}\right) - 12 \cdot \left(\frac{2x - 1}{3}\right) = 12 \cdot 1 \] This simplifies to: \[ 3(3x - 3) - 4(2x - 1) = 12 \] ### Step 4: Distribute the terms Now we distribute: \[ 9x - 9 - 8x + 4 = 12 \] ### Step 5: Combine like terms Combine the \(x\) terms and the constant terms: \[ (9x - 8x) + (-9 + 4) = 12 \] This simplifies to: \[ x - 5 = 12 \] ### Step 6: Solve for \(x\) Add 5 to both sides to isolate \(x\): \[ x = 12 + 5 \] Thus, \[ x = 17 \] ### Step 7: Verification To verify, we substitute \(x = 17\) back into the original equation: \[ \frac{3(17) - 3}{4} - \frac{2(17) - 1}{3} \] Calculating each term: \[ \frac{51 - 3}{4} - \frac{34 - 1}{3} = \frac{48}{4} - \frac{33}{3} \] This simplifies to: \[ 12 - 11 = 1 \] Since both sides of the equation are equal, our solution is verified. ### Final Solution Thus, the solution to the equation is: \[ \boxed{17} \]
