Let's factor out first. 2(-5x+4)+4x-5 = -10x+8+4x-5. If we combine like terms, -10x+8+4x-5 is -6x+3. Now our equation looks like this:

-6x+3 = -3.

If we move over the 3 on the left to the right side, we have -6x = -6. Divide both sides by -6, and we get our answer.

x = 1

Hope this helped!

Alright, let's start by simplifying the given equation. When multiplying -5x and 4 by 2, you get -10x + 8. Your updated equation is:

-10x + 8 + 4x - 5 = -3

Next, we will combine like terms, which means we will add 4x to -10x and -5 to 8 like so:

-6x + 3 = -3

Then, to isolate the x variable, we're going to make the x term by itself. Start by subtracting 3 from both sides of the equation:

-6x = -6

Once we've done that, to get x by itself, we divide both sides by -6:



This is the solution for x.

Answer:x = 1
