The error is in step 4. The sign was not changed after dividing both sides by -10. Thus, the answer to the inequality should be: -27/10 ≥ x.

<h3>How Negative Number Changes Inequality Sign?</h3>

When we divide or multiply two sides of an inequality by a negative number, the inequality sign is changed to the opposite, i.e. from < to > or from > to <.

In step 4, the sign was not changed after dividing both sides by -10.

The answer should be, -27/10 ≥ x.
