2х-5х+5=-4=0

It looks like there may be a slight error in your equation as it contains two equal signs. I assume you meant to set either the left side or right side equal to zero.

Let's correct the equation to solve for \( x \).

Assuming you meant:

\[ 2x - 5x + 5 = -4 \]

First, simplify the left side:

1. Combine like terms: \[ 2x - 5x = -3x \] So, the equation becomes: \[ -3x + 5 = -4 \]

2. Next, isolate \( x \): \[ -3x = -4 - 5 \] \[ -3x = -9 \]

3. Divide by -3: \[ x = \frac{-9}{-3} = 3 \]

Thus, the solution is:

\[ x = 3 \]

If you meant something different, please provide the corrected equation!
