Answer:

The two numbers are 28 and 35.

Step-by-step explanation:

x + y = 63  

x - y = 7  

Get one equation with one variable. We can't solve for a variable if we had two variables in one equation.

Add the two equations together.  

2x = 70  

x = 35  

You see, the y's canceled out and we can solve for x.  

Now plug x back in to solve for y.  

35 - y = 7  

-y = -28  

y = 28
