\"Joel has twice as many cd's as mary\" ___ j = 2m\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"Subtracting 7 from the number of cd's joel has and dividing by 3 equals the number of cd's blake has\"
\n" ); document.write( "___ (j - 7) / 3 = b\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ [(2m) - 7] / 3 = (25)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2m - 7 = 75
\n" ); document.write( "
