Skip a page for the toc Lesson 16 Solving one step equations Goal: Get the variable on one side of the equation by itself Method: Use inverse operations to eliminate any other terms or numbers. Remember: if you do something to one side of an equation, you must do the same thing to the other side to maintain equality 𝑥−11=17 +11 +11 𝑥 =28
