8x + 7y = 37
2y = 4x - 2
------
Modify for elimination:
8x + 7y = 37
8x - 4y = 4
------
Subtract and solve for "y":
11y = 33
y = 3
----
Solve for "x":
8x + 7y = 37
8x + 7*3 = 37
8x = 16
x = 2

Hi,

 2y = 4x - 2   0r  y = 2x-1

8x + 7y = 37 

8x + 7(2x-1) = 37    | Substituting for y

8x + 14x -7 = 37

    22x = 44

      x = 2  and y = 3   

CHECKING our answer***

Using 8x + 7y = 37 

      16 + 21 = 37
