The units digit of a two-digit number is double the tens digit.If the digit are reversed,the new number is 27 more than the original number.determine the digits. \n" ); document.write( "--------- \n" ); document.write( "Equations: \n" ); document.write( "u = 2t \n" ); document.write( "10u+t = 10t+u+27 \n" ); document.write( "----- \n" ); document.write( "Substitute for \"u\" and solve for \"t\": \n" ); document.write( "10(2t)+t = 10t+(2t) + 27 \n" ); document.write( "21t = 12t+27 \n" ); document.write( "9t = 27 \n" ); document.write( "t = 3 \n" ); document.write( "--- \n" ); document.write( "u = 2t = 6 \n" ); document.write( "--- \n" ); document.write( "Ans: 10t+u = 36 \n" ); document.write( "========================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "========================== \n" ); document.write( " |
