Question

2. Add :
(i) - 4а-у, - 7а-у, - 10a°у, – зау
(iii) 9xyz, - Зzyx, — 5xzy​

Answer 1

Answer:

= -11a - 12y - 3ay & = xyz

Step-by-step explanation:

1.

  = (- 4а-у)+ ( - 7а-у) +  (- 10a°у) + ( – зау)

= -4a - y - 7a -y - 10×1×y  - 3ay

= -4a - 7a - y-y - 10y - 3ay

= -11a - 12y - 3ay

2.

= (9xyz) +(- Зzyx) +  (— 5xzy​)

= 9xyz - 3zyx - 5xzy

= 9xyz - 3xyz - 5xyz

= 9xyz - 8xyz

= xyz
