Question

0,3(6-3y)=4.5-0,8(y-9)

Answer 1

Ответ:

-99 = у

Объяснение:

0,3(6-3y)=4.5-0,8(y-9)

1,8 - 0,9у = 4,5 - 0,8у + 7,2

1,8 = 0,1 у + 11,7

-9.9 = 0,1 у

-99 = у

Answer 2

To solve the equation 0.3(6 - 3y) = 4.5 - 0.8(y - 9), you can follow these steps:

1. Distribute the constants on both sides of the equation to simplify it:

   0.3 * 6 - 0.3 * 3y = 4.5 - 0.8 * (y - 9)

2. Perform the multiplications on both sides:

   1.8 - 0.9y = 4.5 - 0.8y + 7.2

3. Combine like terms on each side of the equation:

   1.8 - 0.9y = 4.5 - 0.8y + 7.2

4. Move all the terms involving y to one side of the equation and the constants to the other side:

   -0.9y + 0.8y = 4.5 + 7.2 - 1.8

5. Simplify the equation:

   -0.1y = 10.8

6. Divide both sides by -0.1 to solve for y:

   y = 10.8 / -0.1 y = -108

So, the solution to the equation is y = -108.
