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

x+ y = -2

   2x = 2

    x = 1   and y = -3    +1+%2B+y+=+-2%2C+++y+=+-3

Ordered pair(x,y) that is the solution for this system is (1,-3)
