Answer 2

The value of (a + b-3) - (b-a +3) + (a-b+ 3) will be (3a-b-3).

Given,

(a + b-3) - (b-a +3) + (a-b+ 3).

To find,

The value of (a + b-3) - (b-a +3) + (a-b+ 3).

Solution,

The value of (a + b-3) - (b-a +3) + (a-b+ 3) will be (3a-b-3).

We can easily solve this problem by following the given steps.

According to the question,

(a + b-3) - (b-a +3) + (a-b+ 3)

We know that the terms with the same variables can be added or subtracted.

So, the given expression can be re-written as follows:

a+b-3-b+a-3+a-b+3

Adding the term with variable a,

3a+b-3-b-b+3-3

Adding the terms with variable b,

3a+b-2b+3-3-3

3a-b+3-6

3a-b-3

Hence, the value of (a + b-3) - (b-a +3) + (a-b+ 3) is (3a-b-3).
