Question

add 20a+b-c with a-20b+c​

Answer 1

As per the data given in the question,

We have to determine the sum of the given expression.

As it is given that,

$(20a+b-c) \:and \:(a-20b+c)$

As for adding both the expression,

We need to add terms containing "a" with the terms containing "a" and the terms containing "b" with terms containing "b",

We will get the sum as,

$(20a+b-c) +(a-20b+c)\\=>20a+b-c+a-20b+c\\=>20a+a+b-20b -c+c\\21a-19b$

Hence, sum of the given expression will be 21a - 19b.

Answer 2

Answer:

The addition of 20a+b-c with a-20b+c is 21a-19b.

Step-by-step explanation:

To find -

The addition of 20a+b-c with a-20b+c​

Solution-

As per given there are two terms,

$20a+b-c$ and $a-20b+c$.

= $(20a+b-c) + (a-20b+c)$

= $20a+b-c + a-20b+c$

= $21a - 19b$

The addition of 20a+b-c with a-20b+c is 21a-19b.
