-8c+5c =-3c

Answer 2

To add  : $2a + 3b + 5c$ and $6a - 7b -8c$

Solution :

• As per the data given in the question, we have to find the value of the expression.

• Adding two or more numbers together is known as an addition.
• Addition as denoted by(+).
• Properties of addition are as follows

1. Identity property of zero.
2. Inverse property.
3. Commutative property.
4. Associative property.

• Here , while adding both the terms we add like terms together .
• Therefore on solving  we get ,

        $(2a + 3b + 5c ) +( 6a - 7b -8c )$

       $= 8a -4b -3c$  

Hence , sum of $2a + 3b + 5c$ and $6a - 7b -8c$  is $8a -4b -3c$ .
