let c = C's age now
\n" ); document.write( "let s = S's age now
\n" ); document.write( ":
\n" ); document.write( "write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( "\"The sum of Sonny's and Cely's ages is 81.\"
\n" ); document.write( "c + s = 81
\n" ); document.write( ":
\n" ); document.write( "\" Three years ago, Sonny's age is Cely's age now.\"
\n" ); document.write( "s - 3 = c
\n" ); document.write( "substitute (s-3) for c in the 1st equation. find s:
\n" ); document.write( "(s - 3) + s = 81
\n" ); document.write( "2s - 3 = 81
\n" ); document.write( "2s = 81 + 3
\n" ); document.write( "2s = 84
\n" ); document.write( "s = \"84%2F2\"
\n" ); document.write( "s = 42 is S's age now
\n" ); document.write( "then
\n" ); document.write( " c + 42 = 81
\n" ); document.write( "c = 81 - 42
\n" ); document.write( "c = 39 is C's age now
\n" ); document.write( ":
\n" ); document.write( " How old will they be 2 years from now?
\n" ); document.write( "Add 2 yrs to their present ages and you have it \n" ); document.write( "
\n" );
