Q: Solve the inequality -x/2 + 4 > 0. What is the solution set?
Solution: -x/2 + 4 > 0 => -x/2 > -4 => x < 8.
Steps: 5
Step 1: Start with the inequality -x/2 + 4 > 0.
Step 2: To isolate -x/2, subtract 4 from both sides: -x/2 > -4.
Step 3: Now, we need to get rid of the negative sign in front of x. To do this, multiply both sides of the inequality by -2. Remember, when you multiply or divide by a negative number, you must flip the inequality sign.
Step 4: After multiplying by -2, the inequality becomes x < 8.
Step 5: The solution set is all values of x that are less than 8.
