Question

A) 0,2 (3x - 4) = 1,6 ( x - 2); 6) 3- (1 -) - 5- (x + 2) = 1 - 4x

Answer 1

Ответ:

А)

0,6-0,8=1,6х-3,2

0,6х-1,6х=-3,2+0,8

-х=-2,4

6)

3+1-5-х-2= -4х

-4-х=-4х

3х=4

х=$\frac{4}{3}$

Answer 2

To solve the equations you provided, let's take them one by one:

A) 0.2(3x - 4) = 1.6(x - 2)

First, distribute the coefficients: 0.6x - 0.8 = 1.6x - 3.2

Next, rearrange the terms containing x on one side and the constants on the other side: 0.6x - 1.6x = -3.2 + 0.8 -1x = -2.4

Finally, solve for x by dividing both sides by -1: x = (-2.4) / (-1) x = 2.4

Therefore, the solution to equation A is x = 2.4.

6. 3 - (1 - y) - 5 - (x + 2) = 1 - 4x

Start by simplifying the equation using the order of operations (parentheses first): 3 - 1 + y - 5 - x - 2 = 1 - 4x

Combine like terms: y - x - 5 = 1 - 4x

Move all terms involving x to one side and the constants to the other side: y + 4x - x = 1 + 5

Simplify: y + 3x = 6

The equation 6) simplifies to y + 3x = 6.

Please note that I assumed there was a variable 'y' in equation 6) since it was not explicitly mentioned in the equation. If 'y' was a typo and you meant something else, please let me know, and I'll be happy to help you further.
