One Step Equations

1)Locate the variable.

2)Determine the operation tied to the variable.

3)Use inverse operations on both sides of the equal sign to solve.

** Remember - To "get rid" or "undo" a fraction tied to multiplication or dividion, multiply by the reciprocal!

4)Check your solution!

Two Step Equations

1) Locate the variable.

2) Undo the addition/subtraction.

3) Undo the multiplication/division.

** Remember - To "get rid" or "undo" a fraction tied to multiplication or dividion, multiply by the reciprocal!

4) Check your solution!

"Special Case" Two Step Equations

1) Locate the variable.

2) Undo the multiplication/division.

3) Undo the addition/subtraction.

4) Check your solution!

Multi Step Equations

1) Distribute (if needed).

2) Combine Like Terms (if needed).

3) Solve the remaining equation using the 2 Step Equations steps.
