Step 1: Use the Response area Property to get Response area resulting equation.

Step 2: Use the Response area Property to get Response area resulting equation.

Step 3: There is/are Response area solution(s).

Step 4: Simplify the resulting equation from the response area property.

Step 5: Solve the equation to find the value(s) of the unknown variable.

Step 6: Check the solution(s) obtained by substituting them back into the original equation.

Step 7: If the solution(s) satisfy the original equation, then they are valid solutions. If not, repeat steps 4-6 until valid solution(s) are found.
