\

The equation is  \"\"

\

Write two cases:

\

Case-1: \"\".

\

\"\"

\

Case-2: \"\"

\

\"\"\"\"

\

Solve the equation for Case-1.

\

Subtraction property of equality: if \"\", then \"\".

\

\"\"

\

\"\"                 (Subtract 5 from each side)

\

\"\"                       (Apply Additive inverse property: \"\")

\

\"\"                             (Apply Additive identity property: \"\")

\

 \"\"                                  (Subtract:\"\") \"\"

\

 Check:

\

To check the solution, substitute \"\" in original equation. 

\

  \"\"

\

  \"\"                              (Add: \"\")

\

  \"\"                                (The absolute value of 18 is 18)

\

Compare the values the equation is true. \"\"  is a solution.\"\"

\

Solve the equation for Case-2.

\

\"\"

\

 \"\"             (Subtract 5 from both sides)

\

 \"\"                   (Apply Additive inverse property: \"\")
