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!
