Objectives: To transform literal equations.

Definition:  Literal Equation: equation involving two or more variables.  Formulas are special types of literal equations.

Familiar Formulas:  A = ½ bh  A = bh  D = rt  Y = mx + b

 What does “solve for x” mean?

 Solve for x: y = 6x – 3z

Solve and state any restrictions :  Solve for h: A = ½ bh  Solve for w: V = lwh

Solve and state restrictions:  Solve for x: y = 4x – 3  Solve for b:  Solve for g: z – br = p
