\n" ); document.write( "Let t = Tony's age in yrs
\n" ); document.write( "Let g = granddad's age
\n" ); document.write( ":
\n" ); document.write( "\" his age in months will be the same as his grandfathers in years.\"
\n" ); document.write( "g = 12t
\n" ); document.write( ":
\n" ); document.write( "\"combined ages will be 78\"
\n" ); document.write( "g + t = 78
\n" ); document.write( "replace g with 12t
\n" ); document.write( "12t + t = 78
\n" ); document.write( "13t = 78
\n" ); document.write( "t = $\"78%2F13\"$
\n" ); document.write( "t = 6 yr is T's age
\n" ); document.write( "then obviously, 72 is G's age
\n" ); document.write( " \n" ); document.write( "
