H (x) = - 4x+3; when h (x) = 11

To solve this, since you know that h (x) is 11 and that it also equals - 4x+3, you set them equal to one another which would look like this: 11=-4x+3.

Then, to solve for x, which is what I am assuming the question is asking, you would subtract 3 from both sides to isolate - 4x, which would result in this:

-4x=8

Now, to solve for x, divide both sides by - 4, and you get your answer which is x=-2
