let the first interest is x
\n" ); document.write( "then the second one will be x+1\r
\n" ); document.write( "\n" ); document.write( "so the total interest is $\"4000x%2F100+%2B+5000%28x%2B1%29%2F100+=+40x+%2B+50%28x%2B1%29+=+90x%2B50\"$ \r
\n" ); document.write( "\n" ); document.write( "so $\"90x+%2B+50+=+500\"$ \r
\n" ); document.write( "\n" ); document.write( "then $\"90x+=+500-50\"$
\n" ); document.write( " $\"90x+=+450\"$
\n" ); document.write( " $\"x+=+450%2F90\"$
\n" ); document.write( " $\"+x+=+5+\"$ \r
