Question

4) a-2b - [3a-6b-{2a-C+(a-4b+c)}]
Solution:-​

Answer 1

Answer:

= a-2b-[3a-6b-{2a-C+(a-4b+c)}

= a-2b-[3a-6b-2a+C+a-4b+c]

= a-2b-3a+6b+2a-C-a+4b-c

= 3a-3a-2b+10b-2c

= 8b-2c

Answer 2

Step-by-step explanation:

=a-2b-[3a-6b-{2a-c+a-4b+c)}]

=a-2b-[3a-6b-{3a-4b}]

=a-2b-[3a-6b-3a+4b]

=a-2b-[-2b]

=a-2b+2b

=a [Ans]
