• What is the equation used to isolate the term with $y$?


  $2y - 7 =$$13$
• What does the equation $2y =$$20$ represent?


  The term with $y$ is isolated
• What is the result after adding 7 to both sides of $2y - 7 =$$13$?


  $2y =$$20$
• What do we add to both sides of the equation?

  7
• What operation is performed to isolate $y$ in the equation?


  Add 7 to both sides
• How can we find the value of $y$ after simplifying?


  By dividing both sides by 2
• How does adding 7 to both sides affect the equation $2y - 7 =$$13$?


  It eliminates the -7 from the left side
• Why do we divide both sides of the equation by $2$?


  To keep the equation balanced
• Why do we add 7 to both sides of the equation?

  To keep it balanced
• What is the result of dividing $2y$ by $2$?


  $y$
• What is the first step to solve the equation $2y =$$20$?


  Divide both sides by $2$
• What is the process to solve the equation $2y =$$20$?


  1. Divide both sides by $2$
  2. Simplify to get $y =$$10$
  3. Interpret the result in context
• What happens when we add 7 to $2y - 7$?


  It cancels out the -7
• What is the result of dividing $20$ by $2$?


  $10$
