Question

0,3(6-3y) = 4,5 -0,8(y-9)

Answer 1

Відповідь:

y = -99

Покрокове пояснення:

0,3(6-3y) = 4,5 -0,8(y-9)

1,8-0,9y=4,5-0,8y+7,2

1,8-0,9y=11,7-0,8y

-0,9y+0,8y=11,7-1,8

-0,1y=9,9

y = -99

Answer 2

Пошаговое объяснение:

1,8-0,9y=4,5-0,8y+7,2

-0,9y+0,8y=11,7-1,8

-0,1y=9,9

y=99

Answer 3

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

1. Distribute the constants on the left side and right side of the equation:

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

2. Simplify the equation by performing the multiplications:

   1.8 - 0.9y = 4.5 - 0.8y + 7.2

3. Move like terms to each side of the equation to isolate the variables:

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

4. Combine like terms on both sides of the equation:

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

   -0.1y = 10.5

5. Now, solve for y by dividing both sides of the equation by -0.1:

   (-0.1y) / (-0.1) = 10.5 / (-0.1)

   y = -105

So, the solution to the equation is y = -105.
