Algebra.Com's Answer #613581 by josgarithmetic(39618)![]() ![]() ![]() You can put this solution on YOUR website! \"Sum of a two-digit number is 13\", means the two digit number IS 13. You would then already know the number and not solve for it.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "If the sum OF THE DIGITS of a two-digit number is 13, then this is very different.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "t, the tens digit \n" ); document.write( "u, the units or ones digit \n" ); document.write( "Number is 10t+u. \n" ); document.write( "t+u=13. \n" ); document.write( "The \"next\" part of the description means, (10t+u)*6=456.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Solve this system: \n" ); document.write( " |
