3.8 SOLVING EQUATIONS AND FORMULAS SWBAT To Solve Equations for Given Variables Use Formulas for Real World Problems.

3.8 SOLVING EQUATIONS AND FORMULASSWBAT• To Solve Equations for Given Variables• Use Formulas for Real World Problems.

Solving For Variables…• The equations we have dealt with have had only one type

variable.

• Equations can have two or more different variables.

• Some we know as Formulas.

Solving Equations for Specific Variables…

• Treat the equation as you would any other. UNDO operations!• You know the variable is solved for when it is isolated on one

side of the equation, equal to everything else.• Watch the videos below and copy into your notes.
