Answer 1

Solution:

To solve the given expression, let's simplify each term step by step:

1) 13а - 8(7а - 1) + 2 - 2(2р - 1) + 4 + 3

First, let's simplify the expression inside the parentheses:

7а - 1

Next, let's distribute the -8 to the expression inside the parentheses:

-8(7а - 1) = -56а + 8

Now, let's simplify the expression inside the second set of parentheses:

2р - 1

Next, let's distribute the -2 to the expression inside the parentheses:

-2(2р - 1) = -4р + 2

Now, let's combine like terms:

13а - 56а + 8 + 2р - 4р + 2 + 4 + 3

Combine the like terms:

(13а - 56а) + (2р - 4р) + (8 + 2 + 4 + 3)

Simplify further:

-43а - 2р + 17

Therefore, the simplified expression is -43а - 2р + 17.

2) 21х - 7 - 4(9х + 3) + 4

First, let's simplify the expression inside the parentheses:

9х + 3

Next, let's distribute the -4 to the expression inside the parentheses:

-4(9х + 3) = -36х - 12

Now, let's combine like terms:

21х - 36х - 12 - 7 + 4

Combine the like terms:

(21х - 36х) + (-12 - 7 + 4)

Simplify further:

-15х - 15

Therefore, the simplified expression is -15х - 15.

3) 33 - 8(11в - 1) - 2в + 5

First, let's simplify the expression inside the parentheses:

11в - 1

Next, let's distribute the -8 to the expression inside the parentheses:

-8(11в - 1) = -88в + 8

Now, let's combine like terms:

33 - 88в + 8 - 2в + 5

Combine the like terms:

(33 - 88в) + (-2в + 8 + 5)

Simplify further:

-88в - 2в + 46

Therefore, the simplified expression is -90в + 46.

4) 6(с + 1) - 6с - 5

First, let's simplify the expression inside the parentheses:

с + 1

Next, let's distribute the 6 to the expression inside the parentheses:

6(с + 1) = 6с + 6

Now, let's combine like terms:

6с + 6 - 6с - 5

Combine the like terms:

(6с - 6с) + (6 - 5)

Simplify further:

1

Therefore, the simplified expression is 1.

In summary, the simplified expressions are: 1) -43а - 2р + 17 2) -15х - 15 3) -90в + 46 4) 1
