The correct Answer is:
To solve the equation \( 6(3x + 2) - 5(6x - 1) = 6(x - 3) - 5(7x - 6) + 12x \), we will follow these steps: ### Step 1: Expand both sides of the equation - Left side: \[ 6(3x + 2) - 5(6x - 1) = 18x + 12 - 30x + 5 = -12x + 17 \] - Right side: \[ 6(x - 3) - 5(7x - 6) + 12x = 6x - 18 - 35x + 30 + 12x = -17x + 12 \] ### Step 2: Set the expanded equations equal to each other Now we have: \[ -12x + 17 = -17x + 12 \] ### Step 3: Rearrange the equation to isolate \( x \) Add \( 17x \) to both sides: \[ -12x + 17 + 17x = 12 \] This simplifies to: \[ 5x + 17 = 12 \] ### Step 4: Subtract 17 from both sides \[ 5x = 12 - 17 \] This simplifies to: \[ 5x = -5 \] ### Step 5: Divide both sides by 5 to solve for \( x \) \[ x = \frac{-5}{5} = -1 \] ### Final Answer Thus, the value of \( x \) is \( -1 \). ---
