The work backward problem-solving strategy can be used to solve a two-step equation by:

• Starting with the solution and reversing each operation to find the original value.

• Guessing the answer and checking if it fits the equation.

• Solving each step in any order you choose.

• Adding random numbers to both sides of the equation.
