Solution:

To solve the equation , start by getting all the terms involving on one side. You can do this by adding and to both sides. This gives you:

Next, isolate by subtracting 20 from both sides:

Now, divide both sides by 2 to solve for :

So, the solution to the equation is .

Let’s check our work: Substitute back into the original equation.

On the left side:

On the right side:

Both sides are equal, confirming is correct!
