Answer 1

Ответ:

6.625

Пошаговое объяснение:

3*(x-7)-(4-5x)=28

3x-21-4+5x=28

8x=53

x=6.625

Answer 2

Ответ:

3x-21-4+5x=28

8x-53=0

8x=53

x=6,6

Answer 3

Let's solve the equation step by step:

3*(x - 7) - (4 - 5x) = 28

First, let's simplify the equation by distributing the 3 and the -1:

3x - 21 - 4 + 5x = 28

Combine like terms:

8x - 25 = 28

Next, let's isolate the variable x. To do that, we'll move the constant term (-25) to the other side by adding 25 to both sides of the equation:

8x - 25 + 25 = 28 + 25

Simplifying:

8x = 53

Finally, we can solve for x by dividing both sides of the equation by 8:

(8x)/8 = 53/8

Simplifying further:

x = 6.625

Therefore, the solution to the equation 3*(x - 7) - (4 - 5x) = 28 is x = 6.625.
