Hi,
what is the x and y if this pls show answer and the steps :) 
1/2(x-y)=2           || |Multiplying thru by 2 so as all denominators = 1
1/2(x+y)+1=0
(x-y)= 4           |||Result of Multiplying thru by 2 so as all denominators= 1 
(x+y)+2=0
x- y = 4          |||Adding EQs in order ot eliminate the y variable
<u>x+ y = -2</u>
   2x = 2
    x = 1   and y = -3    {{{ 1 + y = -2,   y = -3}}}
Ordered pair(x,y) that is the solution for this system is (1,-3)
