Answer:

x= 1/3

y = -8

Step-by-step explanation:

-2y+ y = 8 equation 1

-3x -y =7 equation 2

using equation 1 we have:

-2y+ y = 8

-y = 8

y = -8 equation 3

using equation 3 in equation 2 we have:

-3x -y=7  

-3x -(-8)=7  

-3x +8 =7

-3x = 7-8

-3x = -1

x= 1/3

Answer:

x=1/3       y= -8

step explanation:

-2y+y=   8 then -y=8          y= -8

-3x-(-8) =7

-3x +8 =7

-3x=-1

x=1/3          y= -8
