Let k stand for Karen's age, and m stand for Mary's age.\r
\n" ); document.write( "\n" ); document.write( "2m-8=k
\n" ); document.write( "k+m=28\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substitute k for k=2m-8
\n" ); document.write( "(2m-8)+m=28
\n" ); document.write( "3m-8=28
\n" ); document.write( "3m=36
\n" ); document.write( "m=12\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substitute m for m=12
\n" ); document.write( "k+m=28
\n" ); document.write( "k+(12)=28
\n" ); document.write( "k=16\r
\n" ); document.write( "
