The correct Answer is:
To solve the equation \(6(3x + 2) - 5(6x - 1) = 3(x - 8) - 5(7x - 6) + 9x\), we will follow these steps: ### Step 1: Expand both sides of the equation We start by distributing the numbers outside the brackets. **Left Side:** \[ 6(3x + 2) = 18x + 12 \] \[ -5(6x - 1) = -30x + 5 \] Combining these gives: \[ 18x + 12 - 30x + 5 = -12x + 17 \] **Right Side:** \[ 3(x - 8) = 3x - 24 \] \[ -5(7x - 6) = -35x + 30 \] Combining these gives: \[ 3x - 24 - 35x + 30 + 9x = (3x - 35x + 9x) + (30 - 24) = -23x + 6 \] Now, we can rewrite the equation: \[ -12x + 17 = -23x + 6 \] ### Step 2: Move all terms involving \(x\) to one side To isolate \(x\), we add \(23x\) to both sides: \[ -12x + 23x + 17 = 6 \] This simplifies to: \[ 11x + 17 = 6 \] ### Step 3: Move constant terms to the other side Now, we subtract \(17\) from both sides: \[ 11x = 6 - 17 \] This simplifies to: \[ 11x = -11 \] ### Step 4: Solve for \(x\) Now, we divide both sides by \(11\): \[ x = \frac{-11}{11} = -1 \] ### Step 5: Check the solution We will substitute \(x = -1\) back into the original equation to verify: **Left Side:** \[ 6(3(-1) + 2) - 5(6(-1) - 1) = 6(-3 + 2) - 5(-6 - 1) = 6(-1) - 5(-7) = -6 + 35 = 29 \] **Right Side:** \[ 3(-1 - 8) - 5(7(-1) - 6) + 9(-1) = 3(-9) - 5(-7 - 6) - 9 = -27 - 5(-13) - 9 = -27 + 65 - 9 = 29 \] Since both sides equal \(29\), the solution is verified. ### Final Answer \[ x = -1 \] ---
