Answer 1

Given :--

3a+2b-5c,-4a+b-7c,4a-3b+6c

3a - 4a + 4a + 2b + b - 3b - 5c - 7c + 6c

- a + 4a + 3b - 3b - 12c + 6c

3a + b - 6c (ans)

Some Important points :--

1. First look at the expression and rearrange the like terms, similarly as I did. Placing a, b and c together.

2. Now add or subtract by following points :--

1. - and - is always +.

2. - and + is always -.

Answer 2

Step-by-step explanation:

$solution$

Write the given expressions.

The given expressions are

3a+2b-5c;-4a + b 7c; 4a 3b+ 6c

Now find the sum of these expressions.

Find the sum of the given expressions.

(3a + 2b5c) + (-4a+b7c) +

(4a − 3b + 6c) = 3a + 2b - 5c - 4a +

b7c4a 3b + 6c

Write the like terms together and find the

sum.

(3a 4a + 4a) + (2b + b − 3b) +

(-5c - 7c+ 6c)

=

=(3 −4+4)a +(2+1-3)b+ (-5

=

7+6)c

= 3a + (-6)c

= 3a - 6c

Final answer

<

The sum of 3a + 2b − 5c; −4a + b -

3b + 6cis 3a – 6c.

7c; 4a
