Hey there!

The correct option is .

To solve this, we will start with the equation given:

When solving equations, we want to get by itself on one side of the equal sign, and the value of on the other side. Also, in math, what we do to one side of the equal sign, we must do to the other. So, we want to cancel out the so is by itself, so we subtract, and we must do it to both sides. So subtract both sides by .

Now, we solve it, so , and . So:

Hope this helps, and have a nice day! :)
