Answer 1

Вот,здесь все два номера с решением,все правильно,если что-то непонятно,то спрашивайте

Answer 2

Let's simplify each expression step by step:

А) 3*(8а-4) + 6а

First, distribute the multiplication: 38а - 34 + 6а

Now, combine like terms: 24а - 12 + 6а

Finally, combine the remaining terms: 30а - 12

Answer: 30а - 12

Б) 11с + 5*(8-с)

First, perform the subtraction inside the parentheses: 11с + 5*(8 - с)

Now, distribute the multiplication: 11с + 5*8 - 5с

Now, perform the multiplication: 11с + 40 - 5с

Finally, combine the like terms: 6с + 40

Answer: 6с + 40

В) 2*(у-1) - 2у + 12

First, distribute the multiplication: 2у - 21 - 2у + 12

Now, combine like terms: 2у - 2 - 2у + 12

The '2у' and '-2у' terms cancel each other out, leaving: -2 + 12

Finally, combine the remaining terms: 10

Answer: 10

Г) 16 + 3*(2-3у) + 88

First, perform the subtraction inside the parentheses: 16 + 3*(2 - 3у) + 88

Now, distribute the multiplication: 16 + 32 - 33у + 88

Perform the multiplication: 16 + 6 - 9у + 88

Finally, combine the like terms: 22 - 9у

Answer: 22 - 9у

А) 7р - 2*(3р-1)

First, distribute the multiplication: 7р - 23р + 21

Now, combine like terms: 7р - 6р + 2

Finally, combine the remaining terms: р + 2

Answer: р + 2

Б) -4*(3а+2) + 8

First, distribute the multiplication: -43а - 42 + 8

Perform the multiplication: -12а - 8 + 8

The '-8' and '+8' terms cancel each other out, leaving: -12а

Answer: -12а

В) 3 - 17а - 11*(2а-3)

First, distribute the multiplication: 3 - 17а - 112а + 113

Perform the multiplication: 3 - 17а - 22а + 33

Finally, combine the like terms: 3 - 39а + 33

Answer: -39а + 36

Г) 15 - 5*(1-а) - 6а

First, perform the subtraction inside the parentheses: 15 - 5*(1 - а) - 6а

Now, distribute the multiplication: 15 - 51 + 5а - 6а

Perform the multiplication: 15 - 5 + 5а - 6а

Combine like terms: 10 - а

Answer: 10 - а
