Answer:

x = 14

Explanation:

First step is to set the opposite sites equal to each other (they are congruent)

13 = 2y + 1

and

x = y + 8

Now solve for y in terms of x so you can substitute it in the other equation

x - 8 = y

Plug into equation

13 = 2(x-8) + 1

13 = 2x - 16 + 1 distribute

13 = 2x - 15 simplify

28 = 2x add 15 to both sides

x = 14

I hope this helps
