Question

0.4(6-4у)=1.9+0.5(-3у+7)​

Answer 1

0,4(6-4y)=1,9+0,5(-3y+7)

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

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

-0,1y=3

y=-30

Answer 2

To solve the equation 0.4(6 - 4y) = 1.9 + 0.5(-3y + 7), you can start by simplifying and isolating the variable y. Here's the step-by-step solution:

1. Distribute the constants on the right side of the equation: 0.4(6 - 4y) = 1.9 + 0.5(-3y + 7)

   2.4 - 1.6y = 1.9 - 1.5y + 3.5

2. Combine like terms on both sides of the equation: 2.4 - 1.6y = 5.4 - 1.5y

3. Move all terms involving y to one side of the equation by adding 1.5y to both sides: 2.4 - 1.6y + 1.5y = 5.4 - 1.5y + 1.5y

   2.4 - 0.1y = 5.4

4. Next, subtract 2.4 from both sides to isolate the term with y: 2.4 - 0.1y - 2.4 = 5.4 - 2.4

   -0.1y = 3.0

5. Finally, divide both sides by -0.1 to solve for y: (-0.1y) / (-0.1) = 3.0 / (-0.1)

   y = -30

So, the solution to the equation is y = -30.
