Answer:

The solution is (1, 3).

Step-by-step explanation:

Solving the second equation for x, we get x = y - 2.

Substituting y - 2 for x in the first equation, we obtain y - 2 + y = 4, or

2y = 6

Then y = 3.  

Substituting 3 for y in the 1st equation, we get x + 3 = 4, or x = 1.

The solution is (1, 3).
