Let \"+x+\" = pounds of yarn with 15% wool needed
\n" ); document.write( "\"+.15x+\" = pounds of wool in the 15% yarn
\n" ); document.write( "\"+.6%2A16+=+9.6+\" pounds of wool in the 60% yarn
\n" ); document.write( "--------------------------------------
\n" ); document.write( "\"+%28+.15x+%2B+9.6+%29+%2F+%28+x+%2B+16+%29+=+.33+\"
\n" ); document.write( "\"+.15x+%2B+9.6+=+.33%2A%28+x+%2B+16+%29+\"
\n" ); document.write( "\"+.15x+%2B+9.6+=+.33x+%2B+5.28+\"
\n" ); document.write( "\"+.33x+-+.15x+=+9.6+-+5.28+\"
\n" ); document.write( "\"+.18x+=+4.32+\"
\n" ); document.write( "\"+x+=+24+\"
\n" ); document.write( "24 pounds of yarn with 15% wool is needed
\n" ); document.write( "check:
