Answer:

I) 2x - y = -2x - 2y = 53x + 2y = 10 ---------------- (1)

II) 5x - 2y = 63x + y = 3 ------------------ (2)

III) 2x + 4y = 225x - 2y = -19 ----------- (3)

IV) 3x + y = -7x - y = -3x + y = -7y = -2x ------------ (4)

V) 3x - y = 10y = 2x - 9y = x - 5y = x - 2 ------------ (5)

VI) 2x - 3y = -5 ----------------- (6)
