Let 10x + y = the two digit number
\n" ); document.write( ":
\n" ); document.write( "\"has a ten's digit that is two less the unit's digit.\"
\n" ); document.write( "x = y - 2
\n" ); document.write( ":
\n" ); document.write( "\"The number formed by reversing the digits exceeds the original number by three times the unit's digit.\"
\n" ); document.write( "10y + x = (10x + y) + 3y
\n" ); document.write( "10y + x = 10x = 4y
\n" ); document.write( "10y - 4y = 10x - x
\n" ); document.write( "6y = 9x
\n" ); document.write( ":
\n" ); document.write( " What is the number.
\n" ); document.write( "Replace x with (y-2) in the above equation
\n" ); document.write( "6y = 9(y-2)
\n" ); document.write( "6y = 9y - 18
\n" ); document.write( "+18 = 9y - 6y
\n" ); document.write( "18 = 3y
\n" ); document.write( "y = \"18%2F3\"
\n" ); document.write( "y = 6
\n" ); document.write( "then
\n" ); document.write( "x = 6 - 2
\n" ); document.write( "x = 4
\n" ); document.write( ":
\n" ); document.write( "46 = the two digit number
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the statement:a two-dig
\n" ); document.write( "\" number formed by reversing the digits exceeds the original number by three times the unit's digit.\"
\n" ); document.write( "64 = 46 + 3(6)
\n" ); document.write( "64 = 46 + 18 \n" ); document.write( "
\n" );
