Answer:

x = 23

y = 10

Step-by-step explanation:

Let the two numbers be x and y where x>y

x + y = 33

x - y  = 13             Add

2x = 46               Divide by 2

2x/2=46/2           Do the division

x = 23

=============

Solve for y

x + y = 33               Substitute for x

23 + y = 33             Subtract 23 from both sides.

23-23+y = 33 - 23  

y = 10
