Answer 1

Ответ:

15-1,1y=45+3,9y

-1,1y-3,9y=45-15

-5y=30

5y=-30

y=-6

Answer 2

Ответ: y= -6

Если решение надо то могу написать.

Answer 3

To solve the equation 15 - 1.1y = 45 + 3.9y, we can start by simplifying the equation:

15 - 1.1y = 45 + 3.9y

Let's first move all the terms with "y" to one side of the equation by subtracting 3.9y from both sides:

15 - 1.1y - 3.9y = 45 + 3.9y - 3.9y

Simplifying further:

15 - 5y = 45

Next, let's isolate the term with "y" by subtracting 15 from both sides:

15 - 5y - 15 = 45 - 15

Simplifying:

-5y = 30

To solve for "y," divide both sides of the equation by -5:

(-5y) / -5 = 30 / -5

Simplifying:

y = -6

Therefore, the solution to the equation is y = -6.
