Graph the solution set on a number line

\

\"number

Check:

\

To check, substitute a number less than 51 in inequality \"\".

\

\"\"             (Substitute \"\")

\

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

\

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

\

The inequality is true.                  \"\"

\

The inequality solution is \"\".
