Solving a Formula for a Given Variable

Procedure: (Solving a Formula for a Given Variable)

1. If necessary, multiply both sides by the LCD to clear fractions.

2. Identify the variable to be solved for. Move all terms containing that variable to one side of the equation and all terms NOT containing the variable to the other side.

3. If the variable you are solving for is in more than one term, factor it out.

4. Multiply or divide to get the variable in question alone.
