The correct Answer is:
To solve the inequalities \(3x - 7 > 2(x - 6)\) and \(6 - x > 11 - 2x\), we will break it down into steps. ### Step 1: Solve the first inequality \(3x - 7 > 2(x - 6)\) 1. Distribute on the right side: \[ 3x - 7 > 2x - 12 \] 2. Subtract \(2x\) from both sides: \[ 3x - 2x - 7 > -12 \] \[ x - 7 > -12 \] 3. Add \(7\) to both sides: \[ x > -12 + 7 \] \[ x > -5 \] ### Step 2: Solve the second inequality \(6 - x > 11 - 2x\) 1. Rearranging gives: \[ 6 - x > 11 - 2x \] 2. Add \(2x\) to both sides: \[ 6 + x > 11 \] 3. Subtract \(6\) from both sides: \[ x > 11 - 6 \] \[ x > 5 \] ### Step 3: Combine the results from both inequalities From the first inequality, we have: \[ x > -5 \] From the second inequality, we have: \[ x > 5 \] ### Step 4: Determine the common solution set The more restrictive condition is \(x > 5\). Therefore, the solution set for the combined inequalities is: \[ x > 5 \] ### Final Answer The solution set of the inequalities is: \[ (5, \infty) \]
