Answer:

one number is 8 and the other number is 4.

Step-by-step explanation:

x - y = 4 Solution:

x + y = 12

x  - y =   4

Add the two equations together:

2x = 16

Divide both sides by 2:

x = 8

Solve for y:

Use equation 1 substituting for x:

x + y = 12

8 + y = 12

Subtract 8 from both sides:

y = 4

Answer:

one number is 8 and the other number is 4.

8 + 4 = 12

8 - 4  =  4

Hope this helps!
