The sum of a 2 digit number and the 2 digit number when the digits are reversed is 77. if the difference of the same two numbers is 45, what are the two 2 digit numbers?
+934 XY+YX=77 and XY-YX=45 assuming XY>YX. Don't confuse that XY means X*Y but it means a two-digit integer XY. The numbers 16 and 61 fit these conditions where 61+16= 77 and 61-16= 45.
Hope it helps!
