\n" ); document.write( "minus the units’ digit is 1, and the sum of the digits is 15.
\n" ); document.write( "

Let tens digit be T
\n" );
document.write( "Then hundreds digit = 1 + T, and units digit = T - 1
\n" );
document.write( "Since they SUM to 15, we get: T + 1 + T + T - 1 = 15
\n" );
document.write( "3T = 15
\n" );
document.write( "Tens digit, or 
\n" );
document.write( "Hundreds digit is then: 1 + 5 = 6
\n" );
document.write( "Units digit is then: 5 - 1 = 4
\n" );
