Solving single linear inequalities follow pretty much the same process for solving linear equations. We will simplify both sides, get all the terms with the variable on one side and the numbers on the other side, and then multiply/divide both sides by the coefficient of the variable to get the solution.
A linear inequality is similar to a linear equation, but instead of an equal sign (=), it uses an inequality sign (such as <, ≤, >, ≥ ). These inequalities describe a region of the graph, rather than just a line. Forms of Linear Inequalities: Linear inequalities are formed by combining linear algebraic expressions with inequalities.
Learn linear inequalities for class 11 here. In this article, we are going to learn what is inequality in Math, linear inequalities, graphing of linear inequalities, and examples in detail.
Graphing Linear Inequalities If we have an statement such as x <4 x <4, this means a solution can be any number smaller than 4 4 such as −2, 0, 3, 3.9 − 2, 0, 3, 3.9 or even 3.999999999 3.999999999 as long as it is smaller than 4 4.
One-variable linear inequalities (like x<5) are solved in almost the same way as are one-variable linear equations (like x=5), by isolating the variable.

An inequality, as the name suggests, is a relationship between two quantities that are unequal. One property of real numbers is that they have order. This order allows us to compare numbers and decide if they are equal to each other or one is greater or less than the other. It is easiest to understand inequalities in the context of a number line (see above). This shows us that the numbers are ...
A linear inequality is a mathematical statement that relates a linear expression as either less than or greater than another. The following are some examples of linear inequalities, all of which are solved in this section:

Solving linear inequalities Inequalities are generally solved using the same steps as for equations, except when multiplying or dividing both sides of an inequality by a negative number, in which case you must reverse the direction of the inequality sign.

The graph of a linear inequality in one variable is a number line. Use an open circle for < and > and a closed circle for ≤ and ≥. The graph for x > -3 The graph for x ≥ 2 Inequalities that have the same solution are called equivalent. There are properties of inequalities as well as there were properties of equality. All the properties below are also true for inequalities involving ≥ ...
