Question

2,8 – 3,2х = –4,8 – 5,1х

Answer 1

Ответ:

x=-4

Пошаговое объяснение:

$2.8-3.2x=-4.8-5.1x\\-3.2x+5.1x=-4.8-2.8\\1.9x=-7.6\\x=-7.6/1.9\\x=-4$

Answer 2

Ответ:

5,1х-3,2х=-4,8-2,8

1,9х=-7,6

х=-4

Answer 3

To solve the equation 2.8 - 3.2x = -4.8 - 5.1x for the variable x, you can follow these steps:

1. Start by collecting the x terms on one side of the equation and the constant terms on the other side. You can do this by adding 5.1x to both sides of the equation and adding 4.8 to both sides:

   2.8 - 3.2x + 5.1x = -4.8 - 5.1x + 5.1x + 4.8

Simplify both sides:

(2.8 + 5.1x) - 3.2x = 0

2. Combine the terms on the left side:

   2.8 + 5.1x - 3.2x = 0 2.8 + 1.9x = 0

3. Now, isolate the term with x by subtracting 2.8 from both sides:

   2.8 + 1.9x - 2.8 = 0 - 2.8 1.9x = -2.8

4. Finally, solve for x by dividing both sides by 1.9:

   x = -2.8 / 1.9 x ≈ -1.4737

So, the solution to the equation is approximately x = -1.4737.
