1. Objectives: To transform literal equations.

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

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

4. What does “solve for x” mean? Solve for x:y = 6x – 3z

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

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

7. Solve and state restrictions: Solve for y:q = 3(x – y ) Solve for a:

8. Solve and state restrictions: Solve for b 1. A = ½ h(b 1 + b 2 ) Solve for x. ax + bx – 15 = 0

9. Solve and state restrictions: Solve for x. Solve for x.
