Step-by-step explanation:
To find y :
-x+y= 1
Take this equation as (1)
3x-y= 5
Take this equation as (2)
-3x + 3y = 3
Take (1) and multiply x to make it the same as 3x from (2)
3x - y = 5
Keep (2) the same
3x- 3y = 3
Make 3x in (1) positive
3x - 3y = 3
- 3x - y = 5
Minus (2) from (1) to factor out x
- 4y = - 2
After minus
4y = 2
Cancel out the minus
y =

Bring 4 to the other side and divide 2 by 4
To find x :
- x + ( 1/2) = 1
substitute y with its value
- x = 1/2
bring 1/2 to the other side and minus from 1
x = - 1/2
bring the negative sign to the other side
