Problem Solving 4 Operations

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.
