How to Solve Compound Inequalities - Algebra I
Sunday, November 8, 2015
In this video, you will learn how to solve compound inequalities. An inequality is determined by the symbols greater than, less than, greater than or equal to, and less than or equal to. A compound inequality can be an 'and' compound inequality, or an 'or' compound inequality. In an 'and' compound inequality, the two point son the number line, which represent the solutions to each of the inequalities, are shaded so that the solution of the entire compound inequality is within both points. To solve for the solution, you simply use inverse operations. Solving an inequality is similar to solving an equation, except you don't get an exact solution. To learn more, watch the following video for step by step instructions.
In this video, you will learn how to solve multi-step inequalities. An inequality is determined by the symbols for greater than, less than, greater than or equal to, and less than or equal too. When you have a multi-step inequality, it means that it will require multiple inverse operations to solve for the variable. It is similar to solving multi-step equations, but instead of getting a solid number for the value of the variable, you will get a range. For example, if your solution is 4 and there is a less than symbol, it means that the value of the variable can be any number less than 4.

How to solve Multi Step Inequalities - Algebra I
In this video, you will learn how to solve a one step equation. An equation is two mathematical expressions that are equal to one another. When solving a one step equation, you are solving for the value of the variable. A variable is an unknown value in math that is substituted by a lower case letter, often x. In order to find the value of the variable, you must isolate the variable, or in other words get it by itself. To do this, you must use inverse operations. Inverse Operations are opposite operations. The inverse pairs are addition and subtraction & multiplication and division.
