Question

1,9-0,5(7-3у)=0,4(4у-6)​

Answer 1

Ответ:

y=8

Пошаговое объяснение:

1,9-3,5+1,5y=1,6y-2,4

-1,6+1,5y=1,6y-2,4

1,5y-1,6y=-2,4+1,6

-0,1y=-0,8

y=8

Answer 2

Пошаговое объяснение:

1,9-0,5(7-3у)=0,4(4у-6)

1,9-3,5+1,5у=1,6у-2,4

-1,6+1,5у=1,6у-2,4

1,5у-1,6у=-2,4-1,6

-0,1у=-2,4+1,6

-0,1у=-0,8

у=8

Answer 3

To solve the equation 1.9 - 0.5(7 - 3y) = 0.4(4y - 6), you can follow these steps:

1. Distribute the constants on the left and right sides of the equation: 1.9 - 0.57 + 0.53y = 0.44y - 0.46

2. Simplify the equation by performing the multiplications and additions: 1.9 - 3.5 + 1.5y = 1.6y - 2.4

3. Now, isolate the variables on one side of the equation and constants on the other side: 1.5y - 1.6y = -2.4 - 1.9 + 3.5

4. Combine like terms: -0.1y = -0.8

5. Finally, solve for y by dividing both sides by -0.1: y = -0.8 / -0.1 y = 8

So, the solution to the equation is y = 8.
