Answer 2

Let's simplify the given expressions step by step:

1. 3(-х + (-1)) = -(2х + 3)

   Start by distributing the 3 on the left side: 3 * -х + 3 * (-1) = -(2х + 3)

   -3х - 3 = -(2х + 3)

   Now, distribute the negative sign on the right side: -3х - 3 = -2х - 3

   Next, move the terms involving 'x' to one side and the constants to the other side: -3х + 2х = -3 - 3

   -х = -6

   Finally, divide both sides by -1 to solve for 'x': х = 6

2. 0.3(2 - 4у) = 2(0.4у - 1) - 1.4

   Start by simplifying both sides:

   0.3 * (2 - 4у) = 2 * (0.4у - 1) - 1.4

   Now, distribute the constants on both sides:

   0.6 - 1.2у = 0.8у - 2 - 1.4

   Combine like terms on each side:

   0.6 - 1.2у = -0.6у - 3.4

   Next, move all the terms involving 'у' to one side and the constants to the other side:

   0.6 - 0.6у + 1.2у = -3.4

   Combine the 'у' terms:

   0.6 + 0.6у = -3.4

   Subtract 0.6 from both sides:

   0.6у = -3.4 - 0.6

   0.6у = -4

   Finally, divide both sides by 0.6 to solve for 'у':

   у = -4 / 0.6

   у = -20/3

So, the solutions are:

1. х = 6
2. у = -20/3
