1.	Add the expression:(8/5)x + (11/7)y + (9/4)xy, (-3/2)x – (5/3)y – (9/5)xy
Answer» (8/5)x + (11/7)y + (9/4)xy, (-3/2)x – (5/3)y – (9/5)xy Required sum, [(8/5)x + (11/7)y + (9/4)xy] + [(-3/2)x – (5/3)y – (9/5)xy] Collecting like terms, = [(8/5)x – (3/2)x] + [(11/7)y – (5/3)y] + [(9/4)xy – (9/5)xy] = (1/10)x – (2/21)y + (9/20)xy

Add the expression:(8/5)x + (11/7)y + (9/4)xy, (-3/2)x – (5/3)y – (9/5)xy

Answer»

(8/5)x + (11/7)y + (9/4)xy, (-3/2)x – (5/3)y – (9/5)xy

Required sum,

[(8/5)x + (11/7)y + (9/4)xy] + [(-3/2)x – (5/3)y – (9/5)xy]

Collecting like terms,

= [(8/5)x – (3/2)x] + [(11/7)y – (5/3)y] + [(9/4)xy – (9/5)xy]

= (1/10)x – (2/21)y + (9/20)xy
