Steps to Solving a Linear Equation:
**Goal: Isolate the Variable!!
1. Simplify each side of the equation if needed (combine like terms on the same side of the equal sign)
-Remember that you may need to use the distributive property before combining like terms.
-Be careful when distributing a negative sign.
2. Use inverse order of operations to isolate the variable.
-Order of operations tells us to multiply and divide first then add and subtract
-Therefore the inverse of the order of operations is FIRST Add or Subtract
SECOND Multiply or Divide
3. Always Check your work!!!
***Work carefully and do all your work on the paper! This helps to eliminate errors!

2.3 Solving Multi Step Equations Poster Requirements
Your poster should include:
* A creative title
* 4-5 notes on how to solve multi step equations
* 3 example problems that are not ones we did in class (these should be solved on your poster)
* Have explanations along side of all 3 example problems explaining what you did or why you did that step when solving.
* A visual representation to match an example problem.
* Explanation of your visual representation
* Make sure you are neat
* Use at least 4 colors to help organize all your information
* Double check your work so all information is accurate!
** This poster is worth a quiz grade!
