Question

2а − ( 4а − ( − а + ( − 3а − ( а − 5 ) ) ) ).

Answer 1

Ответ:

Пошаговое объяснение:

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

Answer 2

Ответ: -7а+5.

Пошаговое объяснение:

2а-(4а-(-а+(-3а-(а-5))))=2а-(4а-(-а+(-3а-а+5)))=

=2а-(4а--(-а-4а+5))=2а-(4а+5а-5)=2а-9а+5= -7а+5.

Answer 3

To simplify the expression 2a - (4a - (-a + (-3a - (a - 5)))), you can follow the order of operations (PEMDAS/BODMAS) to remove the parentheses and combine like terms:

1. Start with the innermost set of parentheses:

   • (-a + (-3a - (a - 5)))

2. Work your way outwards:

   • (-a + (-3a - a + 5))

3. Combine like terms within the inner parentheses:

   • (-5a + 5)

4. Now, substitute this simplified expression back into the original expression: 2a - (4a - (-5a + 5))

5. Distribute the negative sign to both terms inside the outer parentheses: 2a - 4a + 5a - 5

6. Combine like terms: (2a - 4a + 5a) - 5

   • (2a - 5) (combine the coefficients of 'a')

So, the simplified expression is -2a + 5.
