Solving Inequalities with Variables on Both Sides
Collect variable terms on one side and constants on the other to solve inequalities with variables on both sides, reversing the sign for negative multiplication in Grade 9 Algebra.
Key Concepts
New Concept An inequality or equation that is always true is called an identity . A contradiction is an inequality or an equation that is never true (false). What’s next Next, you’ll use familiar properties to solve these inequalities, including special cases that result in all or no solutions.
