x = amount at 5% = 4000
\n" ); document.write( "y = amount at 2%
\n" ); document.write( "---
\n" ); document.write( "0.05x + 0.02y = 0.04(x + y)
\n" ); document.write( "0.05*4000 + 0.02y = 0.04(4000 + y)
\n" ); document.write( "0.05*4000 + 0.02y = 0.04*4000 + 0.04y
\n" ); document.write( "0.04y - 0.02y = 0.05*4000 - 0.04*4000
\n" ); document.write( "0.02y = 0.05*4000 - 0.04*4000
\n" ); document.write( "y = ( 0.05*4000 - 0.04*4000 )/0.02
\n" ); document.write( "y = 2000
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "y = amount at 2% = $2000
