\n" ); document.write( " $\"+x+=+%281%2F4%29%2Ax+%2B+%281%2F5%29%2Ax+%2B+231+\"$
\n" ); document.write( " $\"+x+-+%281%2F4%29%2Ax+-+%281%2F5%29%2Ax+=+231+\"$
\n" ); document.write( "Multiply both sides by $\"+20%2Fx+\"$
\n" ); document.write( " $\"+20+-+5+-+4+=+4620%2Fx+\"$
\n" ); document.write( " $\"+11+=+4620%2Fx+\"$
\n" ); document.write( " $\"+x+=+4620%2F11+\"$
