The correct Answer is:
To solve the equation \(\frac{3x}{4} - \frac{1}{4}(x - 20) = \frac{x}{4} + 32\), we will follow these steps: ### Step 1: Eliminate the fractions To eliminate the fractions, we can multiply the entire equation by 4 (the least common multiple of the denominators). \[ 4 \left(\frac{3x}{4}\right) - 4 \left(\frac{1}{4}(x - 20)\right) = 4 \left(\frac{x}{4}\right) + 4(32) \] This simplifies to: \[ 3x - (x - 20) = x + 128 \] ### Step 2: Simplify the equation Now, distribute the negative sign on the left side: \[ 3x - x + 20 = x + 128 \] Combine like terms: \[ 2x + 20 = x + 128 \] ### Step 3: Isolate the variable Next, we will isolate \(x\) by moving \(x\) to one side and constants to the other side. Subtract \(x\) from both sides: \[ 2x - x + 20 = 128 \] This simplifies to: \[ x + 20 = 128 \] ### Step 4: Solve for \(x\) Now, subtract 20 from both sides to solve for \(x\): \[ x = 128 - 20 \] This gives us: \[ x = 108 \] ### Final Answer Thus, the solution to the equation is: \[ \boxed{108} \] ---
