Answer:

x = 2 \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \: \: y = 4.

Step-by-step explanation:

(x \:  \:  \:  \:  \:  \:  \: x + y)  \:  \:  \:  \:  \: =  \:  \:  \:  \:  \: (y - 2 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: 6) \\  \\ x = y - 2 \:  \: or \:  \:  \:  \:  \:  \:  \:  \:  \: x - y =  - 2 \\  \\ and \:  \:  \:  \:  \:  \: x + y = 6 \\  \\ solving \: these \: equations \\  \\ 2x = 4 \\  \\ x = 2 \\  \\ then \:  \: y = 6 - 2 = 4 \\  \\ x = 2 \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \:  \:  \:  \: \: y = 4.
