Answer 1

Ответ:

0.5

Пошаговое объяснение:

-21y-5+5.6y-8=-20.7

-15.4y-13=-20.7

-15.4y=-20.7+13

-15.4y=-7.7

y=0.5

Answer 3

To solve the equation:

-5(4,2y+1) + 4(1,4y-2) = -20,7

Let's distribute the coefficients:

-20 - 10y - 5 + 4 + 16y - 8 = -20.7

Combine like terms:

-20 + 4 - 5 - 8 - 10y + 16y = -20.7

Simplify:

-29 - 10y + 16y = -20.7

Combine like terms again:

6y - 29 = -20.7

Add 29 to both sides:

6y = 8.3

Divide by 6:

y = 8.3 / 6

y ≈ 1.3833

Therefore, the solution to the equation is y ≈ 1.3833.
