• 3-x=x-3 Always, sometimes, or never true?

• Show all calculations and explain all reasoning

• Pass Back Notebooks

• Warm-up

• Main Idea: We can work backwards to “undo” operations and solve for the unknown variable.

• Two Step, Practice

• Word Problems

• Break

• Multistep, Practice

• Assignment

• 1. Draw a line beneath the = sign to show balance

• 2. UNDO from the outside (away from the variable) towards the inside (towards the variable)

• Examples

• Practice

• 1. Draw a line beneath the = sign to show balance.

• 2. EXPAND (distributive property)

• 3. Move all variables to one side

• 4. Combine Like terms

• 5. Solve two-step

• Examples
