Answer:

x = -17

Explanation:

11 - 2x = 45

We first want to subtract 11 from both sides, so that we have the variable and it's factor on its own side. Making the equation:

-2x = 34

Next, we are going to divide each side by the variables' factor, which in this case is -2. However, there is a slightly longer way to do this, but when you're doing it by hand, it is much easier. I will be showing that way below.

So, instead of dividing either side by -2, we are going to divide both sides by 2. Giving us:

-x = 17

This next step is easy peasy. Since the negative is on the variables side and we need the variable to be positive, we just switch the position of the negative to the numerical side. Shown below.

-x = 17

to

x = -17

So, our final answer is x = -17

Hope this helps!
