simply put, an expression has no "equal to" sign (=). and equation has the "equal" to sign and and inequality has either one of these signs <, >
a number sentence contains an equal sign
Yes, when the inequality has a less that or equal to sign, or a greater than sign or equal to sign, then the equal sign can be replaced and get a solution that is common to both the equation and the inequality. There can also be other solutions to the inequality, where as the solution for the equation will be a valid one.
I assume you mean "inequality". An equation has an equal sign; an inequality has one of the inequality signs instead of an equal sign. These signs are: * Greater than * Greater than or equal * Less than * Less than or equal To solve an inequality, the main point to consider is that if you multiply or divide both sides by a negative number, you must invert the inequality sign. For example, if you multiply both sides by (-2), a greater-than sign would need to be changed to a less-than sign.

"x281" is an expression, not an inequality. An inequality is supposed to have an inequality sign, such as "<" or ">".
When you divide both sides of an inequality by a negative number, the inequality sign flips.

There is no inequality since there is no inequality sign.
With the equal sign (=).
No, you only flip the inequality sign if you are dividing by a negative number on both sides of the inequality
When solving an inequality, you must revers the inequality sign when you multiply (or divide) both sides by a negative number.

No. An inequality must have an inequality sign, for example, "<".
