Step-by-step explanation:
# 3x - 5y = -1 1st eq
# x- y = - 1. 2nd eq
#multiply 2 nd eq by 3
so we get 3x-3y =-3 take this 3rd eq
so now subtract 1 and 3 rd eq
3x - 5y =-1
-3x + 3y =3
-2y =2
y=-1
X= -2

Step-by-step explanation:
multiply 2nd equation by 3
then 2nd equation will become
3x-3y=-3. (this is equation no. 3)
subtracting equation 3 from 1
3x-5y=-1
(-)3x-3y=-3
y=-1
put y=1 in equation 1
so we get x=-2
