Ответ: 4

Answer 2

5y+2(y-4)3=42-3y
5y+6y-24=42-3y
5y+6y+3y=42+24
14y=66
Y=66/14

Answer 3

To solve for the variable y in the equation 5y + 2(y - 4)3 = 42 - 3y, you'll need to follow a few steps:

1. First, simplify the equation by applying the distributive property (also known as the distributive law or distributive multiplication).

2(y - 4)3 can be expanded as 2y - 8.

So the equation becomes: 5y + 2y - 8 = 42 - 3y.

2. Now, combine like terms on both sides of the equation. Add 5y and 2y on the left side and add 3y to both sides of the equation.

7y - 3y - 2y = 42 + 8

This simplifies to: 2y = 50.

3. Now, isolate y by dividing both sides by 2:

(2y) / 2 = 50 / 2

y = 25.

So, the solution to the equation is y = 25.
