Пошаговое объяснение:

Answer 2

-1,9y-3,5y=43,8+21
-5,4y=64,8
Y=-12

Answer 3

To solve the equation -21 - 1.9y = 43.8 + 3.5y, follow these steps:

1. First, let's combine like terms. Add 1.9y to both sides and subtract 43.8 from both sides to isolate the variable y.

   -21 - 1.9y + 1.9y = 43.8 + 3.5y + 1.9y

   -21 = 3.5y + 1.9y + 43.8

2. Combine the terms on both sides:

   -21 = 5.4y + 43.8

3. Now, let's isolate y. Subtract 43.8 from both sides:

   -21 - 43.8 = 5.4y + 43.8 - 43.8

   -64.8 = 5.4y

4. Divide both sides by 5.4 to solve for y:

   y = -64.8 / 5.4 ≈ -12

So, the solution to the equation is y ≈ -12.
