There is one big difference in the outcome of an equation and an inequality.
Solving inequalities using addition and subtraction. Solving for inequalities with addition and subtraction requires you to isolate the variable x onto one side with numerical value on the other side. Inequality is a statement of a relationship between two values showing if they are greater than less than or simply not equal to each other. Well one of those rules is called the addition property of inequality and it basically says that if you add a number from one side of an inequality you have to add that same number from the other side of the inequality as well.
Watch the tutorial to see how this looks in terms of algebra. This video is about Solving Inequalities using Addition and Subtraction About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy Safety How YouTube. Inequalities To use subtraction to solve inequalities.
And Why To solve a problem involving safe loads as in Example 4 Part 1 are inequalities with the same solutions. For example x 1 4 7 and x 3 are equivalent inequalities. You can add the same value to each side of an inequalityjust as you did with equations.
Using the Addition Property of Inequality Solve x 2 3 5. How to solve inequalities. The rules for solving inequalities are similar to those for solving linear equations.
However there is one exception when multiplying or dividing by a negative number it is necessary to reverse the inequality sign. Solving Single-Step Inequalities by Addition. Solve x 6 14.
X 6 14. Many simple inequalities can be solved by adding subtracting multiplying or dividing both sides until you are left with the variable on its own. But these things will change direction of the inequality.
Multiplying or dividing both sides by a negative number. Swapping left and right hand sides. Watch this video to learn how to solve inequalities using addition or subtraction.

Solving Inequalities Using Addition and Subtraction Notes and Activities Common Core Standard.
6EEB8 Everything you need to introduce and practice solving inequalities using addition and subtraction. Included in this product. -Solving Inequalities Using Addition and Subtraction.
You will see that the process for addition and subtraction of inequalities is the same as for equations as you continue to use inverse operations to solve them. There is one big difference in the outcome of an equation and an inequality. In an equation you find the solution and in an inequality.
Before beginning the exit ticket I will ask students to discuss how to solve addition and subtraction inequalities. Then students will take the exit ticket. There are 5 questions on the exit ticket and each will be worth 1 point including problem 5.
Students will earn 1 point for noting that the solutions of the given equation and inequality are different because in the equation m can only equal 3 whereas in the inequality.
