Question

Work sheet add a+b-1, b-a+1, -1-26

Answer 1

Answer:

Their sum is 2b - 27

Step-by-step explanation:

We know that we can only add the like terms and not the unlike ones. Therefore we will first segregate the like terms and add them. Here we have to add the given three of the expression which is as follows:

$a+b-1, b-a+1, -1-26$

Therefore we add them as follows:

$a+b-1 + b-a+1 + ( -1-26)$

here we will separate the like terms and then we will just simply add.

∴ $a - a + b + b + 1 - 1 -1 - 26$

= $2b - 27$

Therefore after summing all the above three we get 2b - 27.
