6% account has x dollars
\n" ); document.write( "8% account has 18000-x dollars
\n" ); document.write( "Interest = Principle * Rate * Time
\n" ); document.write( "Interest from 6% account = x(0.06)(1) = 0.06x
\n" ); document.write( "Interest from 8% account = (18000 - x)(0.08)(1) = 0.08(18000 - x)
\n" ); document.write( "Total interest:
\n" ); document.write( "0.06x + 0.08(18000 - x) = 1290
\n" ); document.write( "0.06x + 1440 - 0.08x = 1290
\n" ); document.write( " -1440 -1440
\n" ); document.write( " -0.02x = -150
\n" ); document.write( " x = 7500
\n" ); document.write( "6% account has 7500 which earns 450 interest
\n" ); document.write( "8% account has 18000-7500 or 10500 dollars which earns 840 interest
\n" ); document.write( "checks out to give a total of 1290 interest
\n" ); document.write( "
