Answer: 9, 11 (or for the picture 48 and 52)

Step-by-step explanation:

The sum of two numbers (x, y) is 20;

x+y=20

One is 2 greater than than the other;

y=x+2

Now, we can put that in for y;

x+(x+2)=20

And solve;

2x+2=20

2x=18

x=9

Now, substitute in the value of x into the second equation;

y=9+2

And we get our answer.

y=11

My explanations are bad :(
