\"\"

\

The original function is \"\"

\

Write \"\" as \"\" or \"\"

\
\

\"\"

\

First solve the case \"\".

\

\"\"               (Subtract 5 form each side)

\

\"\"                     (Additive inerse property: \"\") 

\

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

\

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

\

\"\"

\

Next solve the case \"\".

\

\"\"          (Subtract 2 form each side)

\

\"\"                 (Additive inerse property: \"\")

\

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

\

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

\

\"\"

\

First, draw a number line.
