<font color="black" face="times" size="3">Answers: x = 2, y = -1


----------------------------------------------------------------------------

To get these answers, you simply equate the corresponding pieces of the two matrices. 
The top left corner of the left and right matrices are x and 2 respectively. Those entries must be the same for the entire two matrices overall to be equal. Therefore, x = 2.


Through similar reasoning, the top right corners must also be equal, so 2y = -2 leads to y = -1


As a check, note how the bottom left corners are 4 and 2x. So 4 = 2x which solves to x  = 2, confirming our prior solution above.


Finally, the bottom right corners equate to get 6 = -6y and solve to get y = -1. This backs up the other solution.
