Answer 2

Given:

We have given a statement which is From the sum of (3a - b + 11) and (- b-11), subtract (3a-b-11)​.

To Find:

We have to simplify the statement?

Step-by-step explanation:

• For simplifying the given statement first of all we will add the values of  (3a - b + 11) and (- b-11),

• For adding the value we will write it as (3a - b + 11) and (- b-11),

       $(3a - b + 11) + (- b-11),$

• Now take the like terms togher and simplify them by adding or subtracting.

        $\Rightarrow 3a - b - b+11-11\\\Rightarrow3a-2b$

• Now from the sum which we get above, we have subtracted 3a-b-11.

        $3a-2b-(3a-b-11)$

• Now the sign of minus before the bracket will change all the sign inside the brackets.

        $\Rightarrow3a-2b-3a+b+11$

• Now take like terms together and simplify them.

        $\Rightarrow 3a-3a-2b+b+11\\\Rightarrow-b+11$

Hence, the final answer is -b+11.
