Question

-5а-(2а-(7а-(4в-3а)))

Answer 1

- 5a - (2a - (7a - (4b - 3a))) = - 5a - (2a - (7a - 4b + 3a)) = - 5a - (2a - (10a - 4b)) = - 5a - (2a - 10a + 4b) = - 5a - (- 8a + 4b) = - 5a + 8a - 4b = 3a - 4b

Answer 2

Ответ:

Объяснение:

-5a-(2a-(7a-(4b-3a)))=   =  -5a-(2a-(7a-4b+3a))=  -5a-(2a-7a+4b-3a)=

=-5a-2a+7a-4b+3a=   3a-4b

Answer 3

To simplify the expression -5a-(2a-(7a-(4b-3a))), we can start by removing the parentheses and combining like terms. Here's the step-by-step process:

-5a - (2a - (7a - (4b - 3a)))

First, let's simplify the innermost parentheses:

-5a - (2a - (7a - 4b + 3a))

Next, distribute the negative sign to the terms inside the second set of parentheses:

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

Combine the like terms:

(7a - 2a + 3a) - 5a - 4b

8a - 5a - 4b

Finally, combine the like terms once again:

(8a - 5a) - 4b

3a - 4b

Therefore, the simplified expression is 3a - 4b.
