document.write( "\r\n" );
document.write( "x = the number of dimes\r\n" );
document.write( "\r\n" );
document.write( "161-x = the number of nickels.\r\n" );

document.write( "Total money equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    10x + 5*(161-x) = 1150   cents.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The solution\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    x =  = 69.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  69 dimes and 161-69 = 92 nickels.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.  69*10 + 92*5 = 1150  cents total value.    ! correcxt !\r\n" );
