Answer: (3, 1)

Explanation:

1. Since you are given that x=3, you know that the first number in the brackets is 3, so (3, y).

2. Now it is time to find the y-coordinate. You are given the equation x=2y+1, so use that to solve for y

3. To do so, start by substituting 3 into the equation. You will get:

x=2y+1

3=2y+1

4. Now, subtract 1 from both sides

2=2y

5. Lastly, divide both sides by 2. This will give you y=1

Therefore, the ordered pair is (3, 1)
