Answer 1

Frankie likely made a mistake when solving the inequality -2x - 7 > 17. Here are the steps to solve the inequality:

1. Add 7 to both sides of the inequality to isolate the variable: -2x > 24

2. Divide both sides by -2, but remember to flip the inequality sign since we are dividing by a negative number: x
