Question

0,2•(7-2у) =2, 3-0, 3•(у-6) ​

Answer 1

Ответ:

у = -27

Пошаговое объяснение:

0,2•(7-2у) =2, 3-0, 3•(у-6)

0,2*7 - 0,2*2у = 2,3 - (0,3у - 0,3*6)

1,4 - 0,4у = 2,3 - 0,3у + 1,8

- 0,4у + 0,3у = 2,3 + 1,8 - 1,4

- 0,1 у = 2,7

у = 2,7 : (- 0,1)

у = - 27

Answer 2

To solve the equation 0.2(7 - 2y) = 2.3 - 0.3(y - 6), you can follow these steps:

1. Distribute the constants on both sides of the equation:

   0.2 * 7 - 0.2 * 2y = 2.3 - 0.3 * (y - 6)

2. Simplify the expressions on both sides:

   1.4 - 0.4y = 2.3 - 0.3y + 1.8

3. Combine like terms:

   1.4 - 0.4y = 2.3 - 0.3y + 1.8

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

   -0.4y + 0.3y = 2.3 - 1.8 - 1.4

5. Combine like terms on both sides:

   (-0.4y + 0.3y) = 0.5 - 1.4

6. Simplify further:

   -0.1y = -0.9

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

   y = (-0.9) / (-0.1)

Now, solve for 'y':

y = 9

So, the solution to the equation is y = 9.
