Hi,
 x+y = 3
<u> x-y = -1</u>           |Adding the EQuations to eliminate the y variable
 2x = 2
  x = 1  and y = 2    (1 + y = 3) 
Ordered pair(1,2)  the solution for this System of Equations
3x=y+2
 x=y+4
3(y+4) = y+2             ||  Substituting (y+4)  for x
 3y + 12 = y + 2
  2y = -10
   y = -5   and x = -1
Ordered pair(-1,-5)  the solution for this System of Equations
