Answer:

The numbers are 10 and 7

Step-by-step explanation:

I will assume you mean 2 numbers

x+y = 17

x-y =3

Add these two equations together

x+y = 17

x-y =3

------------

2x = 20

Divide by 2 numbers

2x/2 = 20/2

x = 10

Now we need to find  y

x+y =17

10 +y =17

Subtract 10 from each side

10-10+y =17-10

y =7

The numbers are 10 and 7
