Solving Two Step Equations

Solving Two Step Equations

Goal

• To solve multi step equations, use inverse operations to isolate the variable.

When Solving Equations, you always follow the same process

• I: Isolate the Variable

• I: Inverse operation

• O: Other side-What you do to one side of the equation, you must do to the other side

Two Step Equations, follow the same process but you REPEAT the process in order to isolate the variable

• I: Isolate the Variable

• I: Inverse operation

• O: Other side-What you do to one side of the equation, you must do to the other side

• R: Repeat until the variable is alone
