Answer 2

Ответ:

y = -27,5

Пошаговое объяснение:

2,3 + 14 + (-2,89y) = 3 + 2,3 - 3,29y

2,3 + 14 - 2,89y = 5,3 - 3,29y

3,29y - 2,89y = 5,3 - 2,3 - 14

0,4y = -11

$y=\displaystyle\frac{-11}{0,4} =-27.5$

Answer 3

To solve the equation, we need to isolate the variable "y" on one side of the equation. Let's go step by step to solve for "y":

1. Combine like terms on both sides of the equation:

On the left side: 2 + 3 + 14 + (-2.89y) = 19 - 2.89y

On the right side: 3 + 2.3 - 3.29y = 5.3 - 3.29y

Now, the equation becomes:

19 - 2.89y = 5.3 - 3.29y

2. Next, let's move all the terms containing "y" to one side of the equation:

Add 3.29y to both sides: 19 - 2.89y + 3.29y = 5.3 - 3.29y + 3.29y

This simplifies to: 19 + 0.4y = 5.3

3. Now, let's isolate the term containing "y" by moving the constant term to the other side:

Subtract 19 from both sides: 19 - 19 + 0.4y = 5.3 - 19

Simplifies to: 0.4y = -13.7

4. Finally, solve for "y" by dividing both sides by 0.4:

y = -13.7 / 0.4

y ≈ -34.25

So, the solution to the equation is approximately y = -34.25.
