Answer 1

1) у + 4 - у + 1 = 6
   5 не равно 6
2) 3р - 1 - р -3 = 1
   2р - 4 = 1
   2р = 4 + 1
   2р = 5
     р = 2,5

3) 5а + 27а - а = 31а

4) 12b - 17b - b = - 6b

5) 13a + 2b - 2a -b = 11a + b

6) 41x - 58x + 6y -y = 5y - 17x

7) - 5,1a - 4b - 4,9a + b = - 3b - 10a

8) 7,5x + x - 8.5x - 3,5y = - 3,5x

Ребятки, реально элементарные задания. Учитесь пока не поздно, в жизни все пригодиться!

Answer 3

Solution to the Equations:

Let's solve the given equations one by one:

1) (y+4)-(y-1)=6

To solve this equation, we can simplify the expression inside the parentheses first:

(y + 4) - (y - 1) = 6

Expanding the parentheses, we get:

y + 4 - y + 1 = 6

Combining like terms, we have:

5 = 6

This equation is not true, which means there is no solution.

2) 3р-1-(р+3)=1

To solve this equation, we can simplify the expression inside the parentheses first:

3р - 1 - (р + 3) = 1

Expanding the parentheses, we get:

3р - 1 - р - 3 = 1

Combining like terms, we have:

2р - 4 = 1

Adding 4 to both sides of the equation, we get:

2р = 5

Dividing both sides by 2, we have:

р = 2.5

So, the solution to this equation is р = 2.5.

3) 5а + 27а - а + 4

To solve this equation, we can combine like terms:

5а + 27а - а + 4 = 31а + 4

So, the solution to this equation is 31а + 4.

4) 12b - 17b - b + 5

To solve this equation, we can combine like terms:

12b - 17b - b + 5 = -6b + 5

So, the solution to this equation is -6b + 5.

5) 13а + 2b - 2а - b

To solve this equation, we can combine like terms:

13а + 2b - 2а - b = 11а + b

So, the solution to this equation is 11а + b.

6) 41x - 58x + 6y - y

To solve this equation, we can combine like terms:

41x - 58x + 6y - y = -17x + 5y

So, the solution to this equation is -17x + 5y.

7) -5.1а - 4b - 4.9а + b

To solve this equation, we can combine like terms:

-5.1а - 4b - 4.9а + b = -10а - 3b

So, the solution to this equation is -10а - 3b.

8) 7.5x + y - 8.5x - 3.5y

To solve this equation, we can combine like terms:

7.5x + y - 8.5x - 3.5y = -1x - 2.5y

So, the solution to this equation is -1x - 2.5y.

I hope this helps! Let me know if you have any further questions.
