One of the numbers is #1#, and the other number is #22#.

Explanation:

Let first number #= x#
Let second number #= y#

#x + y = 23" " and #
#x+ 21 = y#

Substitute the second equation into the first equation for #y.#

#x + (x +21) = 23#
#2x + 21 = 23#
#2x = 2#
#x = 1#

Plug in this number into one of the two equations to find the other number.

#(1) + 21 = y#
#y = 22#
