Answer 1

Answer:

  see below

Step-by-step explanation:

For the HL theorem to be applicable, the hypotenuses must be the same length:

  x+3 = y-1

and the marked legs must be the same length:

  y-3 = 2x-1

__

Recognizing y-3 = (y-1) -2, we can substitute into the second equation using the first equation:

  (y -1) -2 = 2x -1

  (x +3) -2 = 2x -1 . . . substitute for y-1

  2 = x . . . . . . . . . . add 1-x to both sides

Then the first equation tells us ...

  x+4 = y = 2+4 = 6

The values of x and y are ...

  x = 2, y = 6
