Almost. There's one new rule, which is that whenever you multiply or divide by a negative number, you have to flip the inequality sign. To see why, try achieving the same result without this step, using positive factors and subtraction: the equation must effectively flip itself around the sign.

BeauMore or less, but there are some additional rules for inequalities.Mainly, when multiplying or dividing by a negative number, you need to invert the inequality sign. For example, a "greater-than-or-equal" will become a "less-than-or-equal". You need to be careful here when multiplying or dividing variables - you may need to consider the two cases, that the variable is positive and that it is negative, separately.

How can you use coordinate graphs to solve linear equations and linear inequalities?
To solve it by coordinate graphs you would take a point from the line and plug in the X and Y value into the equations and or inequalities.
How do you solve rational equations and inequalities?
x-2\x+4=x+1\x+10
How do you solve identities on trigonometry?
Unlike equations (or inequalities), identities are always true. It is, therefore, not possible to solve them to obtain values of the variable(s).
How do you solve algebra inequalities?
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.
How do you solve inequalities using addition subtraction multiplication and division.?
In the same wasy as you solve equations except that if you multiply or divide both sides by a negative number, then the inequality changes direction.
