\n" ); document.write( "d = 2s
\n" ); document.write( "m = 2d
\n" ); document.write( "s+22 = (1/2)(m+22)
\n" ); document.write( "------
\n" ); document.write( "Modify::
\n" ); document.write( "Since s = (1/2)d and d = (1/2)m, then s = (1/4)m
\n" ); document.write( "-----
\n" ); document.write( "Substitute for \"s\" and solve for \"m\":
\n" ); document.write( "(1/4)m + 22 = (1/2)m + 11
\n" ); document.write( "(1/4)m = 11
