First, you must learn to solve equations, since inequalities have some additional complications.Solving equations may require many different methods; but the main method for simple equations is to do the same manipulation on both sides of the equation (e.g., add a number, multiply by a number, etc.), with the objective of having the variable alone on one side. Here is an example:
2x + 1 = 11
The objective is to have the "x" alone on one side, so you need to get rid of the "2" and of the "1" on the left side. It's easier if you first subtract 1 on each side, with the result:
2x = 10
Now you still need to get rid of the "2" on the left (remember, the objective is to have the "x" alone), so you can divide both sides by 2, with the result:
x = 5
That's the solution.

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).
What is the difference between inequalities and equations using adding?
equations have an = sign, inequalities do not
Can a system of equations have more than two inequalities?
A system of equations can have any number of inequalities.

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.
Can a system of equations have more than two inequalities?
A system of equations can have any number of inequalities.
What are the two rules for inequalities which do not occur in equations?
Inequalities are not reflexive. Inequalities are not commutative.
How are equations and inequalities different?
Equations have and can only have a = Inequalities have <, >, greater than or equal to, less than or equal to, or =
Compare and contrast equations and inequalities?
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.
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.
