Q.1 Simplify the following expression.
(3a+4b-5c)+(2a-7b-6c)+(8a-5b+9c)​

Answer 1

Answer:

13a-8b-2c

Explanation:

First, open the brackets:

3a+4b+5c+2a-7b-6c+8a-5b+9c

Then group the like terms together:

3a+2b+8a    +4b-7b-5b    -5c-6c+9c

Thewn perform the operations by sequence:

3a+2b=5a

5a+8b=13a

4b-7b= -3b

-3b-5b= -8b

-5c-6c= -11c

-11c+9c= -2c

Now combine the answers, and you get:  13a -8b -2c
