Let $\"+x+\"$ = amount in 5% account
\n" ); document.write( " $\"+40000+-+x+\"$ = amount in 15% account
\n" ); document.write( " $\"+.05x+\"$ = interest earned @ 5%
\n" ); document.write( " $\"+.15%2A%28+40000+-+x+%29+\"$ = interest earned @ 15%
\n" ); document.write( "------------------------------------------
\n" ); document.write( " $\"+.05x=.15%2A%28+40000+-+x+%29+\"$
\n" ); document.write( " $\"+.05x+=+6000++-+.15x+\"$
\n" ); document.write( " $\"+.2x+=+6000+\"$
\n" ); document.write( " $\"+x+=+30000+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+40000+-+x+=+40000+-+30000+\"$
\n" ); document.write( " $\"+40000+-+30000+=+10000+\"$
\n" ); document.write( "$30,000 is in 5% account
