In the equation
4p = 20
 the variable, p, is being multiplied by 4. How should you show your work to isolate the variable and solve the equation?

• Multiply both sides by 4.
  The solution is x = 80.
• Subtract 4 from both sides. 
  The solution is p = 16.
• Add 4 to both sides. The solution is p = 24.
• Divide both sides by 4. The solution is p = 5.
