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
