Question 795385
cant really solve this using substitution, you can solve it using the subtraction/addition method...

x + y = 2
x - y = -2

add the lines together to get...

x = 0

plug that number into the original equation to find the value of y

0 + y = 2
0 - y = -2

y = 2

leave your answer in ordered pair  (0,2)
