equations have an = sign, inequalities do not

The main difference is that when solving inequalities, if you multiply or divide by a negative number you have to be careful, since you then also have to switch the sign (for example, change a "less-than" sign to a "greater-than" sign). If you multiply or divide by an expression that contains a variable, you have to consider the two cases: that such an expression might be positive, or that it might be negative.

Compound inequalities are inequalities that have more than one sign, for example, 5

Algebraic inequalities can be solved in the same fashion as algebraic equations. The goal here, as in algebraic equations, is to isolate the variable. The one thing to remember, however, is that when dividing or multiplying both sides by a negative number, one must switch the inequality sign.

Since there is no inequality sign, those are not inequalities. An inequality sign is normally one of the following: greater than; less than; great-or-equal; less-than-or-equal.

Inequalities and equations are both the same because they are both mathematical expression and they both use the same steps EXCEPT for the end. Inequalities and equations are both different because equations have an equal sign, the answer is not an interval, and the answer is a specific answer. Not a range. While inequalities don't have an equal sign, its answer is an interval, and it's answer is in a range.

Somewhat, but the rules are a bit different for inequalities. Example. -2X > 4 X < - 2 See, sign changes when dividing by negative coefficient.

Inequalities are not reflexive. Inequalities are not commutative.

The definition of equivalent inequalities: inequalities that have the same set of solutions

Instead of using y = mx + b you use y (inequality sign) mx + b. By inequality sign, I mean symbols like
