Final answer:
To solve -x < -29, multiply both sides by -1 and flip the inequality sign, resulting in x > 29.
Step-by-step explanation:
To solve the inequality -x < -29, we need to multiply both sides by -1 to maintain the inequality sign. This gives us x > 29. However, we should also remember to flip the inequality sign when we multiply by a negative number. So, the final solution is x > 29.
