1. 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

+11
+11
𝑥 =28

Check your answer!
Does 28 – 11 = 17?
Yes! So, our answer is correct.
Now you try:
𝑥+7=42 −7 −7
𝑥 =36
