Verified answer

I will rewrite it:

2x - 2y = -1.........(1)

-8x + 2y = -1.......(2)

(1) + (2) gives:

- 6x = -2 => x = 1/3.

Plugging x into (1) gives y = 5/6.

2x-2y= -1........(1)

-8x+2y= -1

8x-2y=1 .........(2)

(2)-(1): 6x=2

x=1/3

put x=1/3 in (1):

2(1/3)-2y= -1

2y= 1 2/3

y= 5/6

2x-2y=-1----------------(1)

-8x+2y=-1--------------(2)

(1)+(2),

2x-8x=-1-1

-6x=-2

x=1/3

substitute x=1/3 into (1)

2(1/3)-2y=-1

2y=2/3+1

2y=5/3

y=5/6

x=1/3

y=5/6
