Question

7с-(2у-(4с+(3у-5с)))

Answer 1

Ответ:

$6c+y$

Объяснение:

$7c-(2y-(4c+(3y-5c)))=7c-(2y-(4c+3y-5c))=\\\\7c-(2y-4c-3y+5c)=7c-2y+4c+3y-5c=6c+y$

Answer 2

To simplify the expression 7c - (2u - (4c + (3u - 5c))), you can follow these steps:

1. Start by simplifying the innermost parentheses:

   7c - (2u - (4c + (3u - 5c)))

   = 7c - (2u - (4c + 3u - 5c))

2. Continue simplifying within the innermost parentheses:

   = 7c - (2u - (3u - c))

3. Now, distribute the negative sign within the parentheses:

   = 7c - 2u + 3u - c

4. Combine like terms:

   = (7c - c) + (-2u + 3u)

5. Simplify further:

   = 6c + u

So, the simplified expression is 6c + u.
