Question

51,2+3,5y=-19-1,9y;​

Answer 1

51,2 + 3,5у = -19 - 1,9у

3,5у + 1,9у = -19 - 51,2

5,4у = -70,2

у = -70,2 : 5,4

у = -13

-------------------------------------------------------------

Проверка: 51,2 + 3,5 · (-13) = -19 - 1,9 · (-13)

                  51,2 - 45,5 = -19 + 24,7

                  5,7 = 5,7

Answer 2

Ответ:

$51.2 + 19 = - 1.9y - 3.5y \\ 70.2 = 5.4y \\ y = 70.2 \div 5.4$

Answer 3

To solve the equation, we'll collect the terms involving "y" on one side and the constant terms on the other side. Let's start by simplifying the equation:

51.2 + 3.5y = -19 - 1.9y

First, let's combine the "y" terms by adding 1.9y to both sides:

51.2 + 3.5y + 1.9y = -19 - 1.9y + 1.9y

Simplifying the equation further:

51.2 + 5.4y = -19

Now, let's isolate the term with "y" by subtracting 51.2 from both sides:

51.2 + 5.4y - 51.2 = -19 - 51.2

Simplifying the equation again:

5.4y = -70.2

Finally, to solve for "y," divide both sides by 5.4:

y = -70.2 / 5.4

y ≈ -13

Therefore, the value of "y" that satisfies the equation is approximately -13.
