Algebra.Com's Answer #366867 by issacodegard(60)![]() ![]() You can put this solution on YOUR website! Let the number be N and let its digits be x (tens) and y (ones). Then, \n" ); document.write( " \n" ); document.write( "We can create two equations from what's given, \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "So, \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Multiply the 1st eqn by 9 and add it to the second to get, \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Divide the second by 9 to get y=8. Then, we have \n" ); document.write( " \n" ); document.write( "So, \n" ); document.write( " \n" ); document.write( "So, the original number was 38. \n" ); document.write( " |
