Algebra.Com's Answer #153397 by MathTherapy(10557) You can put this solution on YOUR website! Let the tens digit be T. Then the units digit is T + 4.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Therefore, the number is 10(T) + (T + 4), or 10T + T + 4 = 11T + 4.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Since the number is 3 less than 4 times the sum of the digits, then we will have:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "(11T + 4) + 3 = 4(T + T + 4), or 11T + 7 = 8T + 16\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "3T = 9\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "T = 3\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The tens digit is 3, and the units digit is 7 (3 + 4). The number is then \n" ); document.write( " \n" ); document.write( " |
