Do the same rules apply when you solve equations and inequalities?

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.

∙ 7y agoMore 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.
How can you use math to solve complex problems?
IF they are math related, write appropriate equations and then apply math rules to solve the equations.

How are word problems with equations different from word problems with expressions?
It may be possible to solve equations. Expressions cannot be solved until they are converted, with additional information, into equations or inequalities which may have solutions.
How do you solve absolute value inequalities?
The absolute value of something is also the square root of the square of that something. This can be used to solve equations involving absolute values.
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.
What does it mean by solving linear systems?
Solving linear systems means to solve linear equations and inequalities. Then to graph it and describing it by statical statements.
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.
How do you apply laplace transform method to solve systems of ordinary DEs?
you apply the Laplace transform on both sides of both equations. You will then get a sytem of algebraic equations which you can solve them simultaneously by purely algebraic methods. Then take the inverse Laplace transform .
How do you solve these trinomials x2-x-63 and x2-3-54?
There are no equations nor inequalities in the question only trinomial expressions. Expressions cannot be solved.
Why do you clear decimals when solving linear equations and inequalities and example?
Even if you keep the decimal, later on you will still have to remove it. It is just an easier way to solve the equation.
