\n" ); document.write( "The interest of $1330 is 4% of the x amount loaned to Alberto plus 5% of the 3x amount deposited in the bank:

\n" ); document.write( "\".04%28x%29%2B.05%283x%29+=+1330\"
\n" ); document.write( "\".04x%2B.15x+=+1330\"
\n" ); document.write( "\".19x+=+1330\"
\n" ); document.write( "\"x+=+1330%2F.19+=+7000\"

\n" ); document.write( "Loan to Alberto: x = $7000
\n" ); document.write( "Deposited in the bank: 3x = $21,000
