Question

(6,8 – 2у)(5у + 15,5) = 0

Answer 1

(6,8-2y)(5y+15,5)=0

6,8-2y=0 5y+15,5=0

2y=6,8-0 5y=0-15,5

2y=6,8 5y= -15,5

y=6,8÷2 y= -15,5÷5

y=3,4 y= -3,1

ОТВЕТ:y=3,4;-3,1

Answer 2

To solve the equation $(6,8 - 2y)(5y + 15,5) = 0$, you need to find the values of $y$ that satisfy the equation.

The equation is a product of two expressions set equal to zero, which means that either the first expression $(6,8 - 2y)$ is equal to zero, or the second expression $(5y + 15,5)$ is equal to zero.

1. Setting the first expression equal to zero: $6.8 - 2y = 0$

Solving for $y$: $6.8 = 2y$ $y = \frac{6.8}{2}$ $y = 3.4$

2. Setting the second expression equal to zero: $5y + 15.5 = 0$

Solving for $y$: $5y = -15.5$ $y = \frac{-15.5}{5}$ $y = -3.1$

So, the possible solutions for $y$ are $y = 3.4$ and $y = -3.1$ that satisfy the given equation.
