When solving Exercise 20, Beth used a to represent the bride’s age and Ben used a to represent the groom’s age. Is one of these approaches preferable to the other? Why or why not?

\n" ); document.write( "The world’s oldest bride was 19 yr older than her groom. Together, their ages totaled 185 yr.
\n" ); document.write( "--
\n" ); document.write( "I prefer to use \"b\" for bride and \"g\" for groom.
\n" ); document.write( "---
\n" ); document.write( "Equations:
\n" ); document.write( "b = g + 19
\n" ); document.write( "b+g = 185
\n" ); document.write( "----
\n" ); document.write( "Substitute for \"b\" and solve for \"g\":
\n" ); document.write( "g+19 + g = 185
\n" ); document.write( "2g = 166
\n" ); document.write( "g = 83 (groom's age)
\n" ); document.write( "----
\n" ); document.write( "solve for \"b\":
\n" ); document.write( "b = g + 19
\n" ); document.write( "b = 83 + 19 = 102 (bride's age)
