System: 4681

Solve the system:
(x + 5) (y-2) = (x-1) (y + 1)
(x + 1) (y + 1) = (x + 5) (y-1)

Correct answer:

x = 2y-3

Step-by-step explanation:

(x+5)(y−2)=(x−1)(y+1) (x+1)(y+1)=(x+5)(y−1)  r1​:(x+5)(y−2)=(x−1)(y+1) r2​:(x+5)(y−1)=(x+1)(y+1)  r1​−r2​  (x+5)(y−2−y+1)=(y+1)(x−1−x−1) x+5=2y+2 y∈R  x=2y−3
