Question

-1,8-x=9+2xпомогите решить

Answer 1

-1,8-x=9+2x
-х-2х=9+1,8
-3х=10,8
х=-3,6

Answer 2

-1,8-9=2x+x ; -10,8=3x ; X=-10,8/3=-3,6

Answer 3

I can help you solve this equation. First, let's rewrite it in a more readable form:

$$-1.8 - x = 9 + 2x$$

To find the value of $x$, we need to isolate it on one side of the equation. We can do this by adding $x$ to both sides and subtracting $9$ from both sides:

$$-1.8 - 9 = 9 + 2x - 9 + x$$

Simplifying, we get:

$$-10.8 = 3x$$

Now, we can divide both sides by $3$ to get the final answer:

$$x = -\frac{10.8}{3}$$

$$x = -3.6$$

You can check your answer by plugging it back into the original equation and verifying that both sides are equal.
