To solve two-step equations, undo the operations
by working backwards.

• Recall the order of operations as you answer
  these questions.
• Dividing by 2
• Subtracting 3

• Example
• Ask yourself,
• What is the first thing we are doing to x?
• What is the second thing?

To undo these steps, do the opposite operations
in opposite order.
