Answer 1

Ответ:

В решении.

Объяснение:

Сначала нужно раскрыть скобки, потом привести подобные члены, потом перенести неизвестное влево, известное вправо и вычислить неизвестную величину.

1) (3y-1)-(2y+4)+y=33

3у-1-2у-4+у = 33

2у = 33+5

2у=38

у=38/2

y= 19;

2) 15x=(6x-1)-(x+18)

15х = 6х-1-х-18

15х-5х = -19

10х = -19

х= -19/10

х= -1,9;

3) 17p-8-(p+7)+15p=0

17p-8-p-7+15p=0

31p = 15

p=15/31;

4) (6m-4)-(7m+7)-m=1

6m-4-7m-7-m = 1

-2m = 1+11

-2m = 12

m= 12/-2

m= -6.

Проверка путём подстановки  вычисленных значений х, у, p и m в уравнения показала, что данные решения удовлетворяют данным уравнениям.

Answer 2

Let's solve each equation step by step:

1. (3y - 1) - (2y + 4) + y = 33

First, simplify the equation by removing the parentheses:

3y - 1 - 2y - 4 + y = 33

Combine like terms:

2y - 5 = 33

Add 5 to both sides of the equation:

2y = 38

Divide both sides by 2:

y = 19

So, y = 19.

2. x = (6x - 1) - (x + 18)

First, simplify the equation by removing the parentheses:

x = 6x - 1 - x - 18

Combine like terms:

x = 5x - 19

Subtract 5x from both sides of the equation:

x - 5x = -19

-4x = -19

Divide both sides by -4:

x = 19/4

So, x = 19/4.

3. p = (6m - 4) - (7m + 7) - m

First, simplify the equation by removing the parentheses:

p = 6m - 4 - 7m - 7 - m

Combine like terms:

p = -2m - 11

We know that p = 0, so we can substitute it into the equation:

0 = -2m - 11

Add 2m to both sides of the equation:

2m = -11

Divide both sides by 2:

m = -11/2

So, m = -11/2.

Therefore, the values of y, x, and p are 19, 19/4, and -11/2, respectively.
