Title: When solving inequalities with greater or equal to sign, what happens when you divide by a negative? Post by: treetreee on Jan 8, 2022 When solving inequalities with greater or equal to sign, what happens when you divide by a negative?
Say you have: \(-x\le 12\) I realize you divide by \(-1\) to solve for \(x\), but if I do, does the sign change to \(x>-12\) or \(x\ge -12\)?

When you switch the sign, you keep the negative. Therefore, the following is correct:
\(−x\le 12\) \(x\ge -12\) |
