The units digit is 1 more than 3 times the tens digit in a two digit number.
\n" ); document.write( " The number represented when the digits are interchanged is 8 times the sum of the digits.
\n" ); document.write( " Find the original number.
\n" ); document.write( ":
\n" ); document.write( "Let x = the 10's digit
\n" ); document.write( "Let y = the units
\n" ); document.write( "then
\n" ); document.write( "10x+y = the number
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\"The units digit is 1 more than 3 times the tens digit\"
\n" ); document.write( "y = 3x + 1
\n" ); document.write( ":
\n" ); document.write( "\"The number represented when the digits are interchanged is 8 times the sum of the digits.\"
\n" ); document.write( "10y + x = 8(x+y)
\n" ); document.write( ":
