D. (2,3)

Explanation:

We already know that x=2, so of we plug in 2 for x, we should get the y value.

Once we plug in 2 for x we should get the equation:

2(2)+3y=13.

Simplify that and we get:

4+3y=13.

Subtract 4 from both sides and we get:

3y=9.

Divide both sides by 3 and we get:

y=3.

This means that your ordered pair should be (2,3).

Hope this helps :)

Answer:

C. 8x - 3y = 5

Step-by-step explanation:

7 - 3(x - y) = 5x + 2

Standard form: Ax + By = C

7 -3x + 3y = 5x + 2

7 -8x + 3y = 2

-8x + 3y = -5

Divide by -1 to each number

8x - 3y = 5
