## RS Aggarwal Class 6 Math Eighth Chapter Algebraic Expressions Exercise 8C Solution

## EXERCISE 8C

**(1) Add:**

(i) 3x, 7x

= 3x+7x =10x

(ii) 7y, -9y

= 7y +(-9y)

= 7y – 9y = -2y

(iii) 2xy, 5xy, -xy

= 2xy + 5xy + (-xy)

= 7xy – xy = 6xy

(iv) 3x, 2y

= 3x + 2y

**(2) Add the following:
**

**(3) Add:**

**(4) Subtract:**

(i) 5x from 2x

= 2x – 5x = – 3x

(ii) –xy from 6xy

= 6xy – (- xy)

= 6xy + xy = 7xy

(iii) 3a from 5b

= 5b – 3a

(iv) -7x from 9y

= 9y – (-7x)

= 9y + 7x

**(5) Subtract:**

**(6) Simplify:
**

Nice but there are not even an example of Q5 8c part 5,6,7 and I had an emergency to do all that questions

But never mind the parts which were there superbly done
