The sum of the digits of a positive two-digit integer is 45 less than the integer.
\n" ); document.write( " What is the tens digit of the integer?
\n" ); document.write( ":
\n" ); document.write( "Let x = 10's digit
\n" ); document.write( "Let y = units
\n" ); document.write( "Then
\n" ); document.write( "10x + y = the two digit integer
\n" ); document.write( ":
\n" ); document.write( "x + y = 10x + y - 45
\n" ); document.write( "Subtract y from both sides
\n" ); document.write( "x = 10x - 45
\n" ); document.write( "Add 45, subtract x, from both sides
\n" ); document.write( "45 = 10x - x
\n" ); document.write( "45 = 9x
\n" ); document.write( "x = \"45%2F9\"
\n" ); document.write( "x = 5 is the tens digit \n" ); document.write( "
\n" );
