Question

4,2x-17,9-8,1x=1,6x+8,5

Answer 1

Ответ:

Пошаговое объяснение:

4,2x-17,9-8,1x=1,6x+8,5

-3,9x - 17,9 = 1,6x + 8,5

-3,9x - 1,6x = 8,5 + 17,9

-5,5x = 26,4

x = 26,4 : (-5,5)

x = -4,8

Answer 2

To solve the equation, we'll combine the terms with "x" on one side and the constant terms on the other side. The goal is to isolate "x" on one side of the equation.

Here's the equation:

4.2x - 17.9 - 8.1x = 1.6x + 8.5

First, let's combine the terms with "x" on the left side:

(4.2x - 8.1x) - 17.9 = 1.6x + 8.5

Now, simplify the left side:

-3.9x - 17.9 = 1.6x + 8.5

Next, let's move all the terms with "x" to one side by adding 3.9x to both sides:

-3.9x + 3.9x - 17.9 = 1.6x + 3.9x + 8.5

Simplify the equation:

-17.9 = 5.5x + 8.5

Now, we want to isolate "x" on one side, so we'll subtract 8.5 from both sides:

-17.9 - 8.5 = 5.5x + 8.5 - 8.5

Simplify the equation:

-26.4 = 5.5x

Finally, to find the value of "x," divide both sides by 5.5:

x = -26.4 / 5.5 x ≈ -4.8

So, the solution to the equation is x ≈ -4.8.
