Identify the steps to solve for b

• Add 6 to both sides

  Then divide both sides by 5

• Add 6 to both sides

  Then multiply both sides by 5

• Subtract 6 from both sides

  Then multiply both sides by 5

• Divide both sides by 5

  Then add 6 to both sides

• Multiply both sides by 6

  Then add 5 to both sides
