Answer: 
 x=-7, y= -20 
Step-by-step explanation: 
2x - y =6
x - y = 13
when I subract (x-y =13 ) from (2x-y =6)
2x -y =6
-x +y=-13
______________
x = -7
substitute x=-7 in the second equation
-7 - y =13
-y = 13 +7
-Y = 20
Y=-20
 x=-7, y= -20 
 
                                
             
                    
              
Answer: 
x= -7/6
y= -25/3
Step-by-step explanation: 
2x-y =6
4
x-y
=13
Firstly, 4x-y=13(-)  =>> - 4x+y=-13
Then we make the sum and result 6x= -7. Result x= -7/6.
 We need to find y. So:  
-y= 6-2x =>>  y= -6 +2x =>> y= -6 +2*(-7/6) =>> y= -6-7/3 =>> y=(-18-7)/3 =>>y= -25/3
