STEP 1
What is this asking? We need to find the value of that makes the equation true. Watch out! Don't forget to keep the equation balanced—whatever you do to one side, you *must* do to the other!
STEP 2
1. Isolate the terms.
2. Isolate the constant terms.
3. Solve for .
STEP 3
We want all the terms on one side.
We have on the left and on the right.
Let's subtract from *both* sides of the equation.
This keeps the equation balanced!
Now, all the terms are neatly on the left side!
STEP 4
We have a hanging out with the .
Let's add to *both* sides to move the constant terms to the right side:
Great! Now the constant terms are on the right, and our term is isolated on the left.
STEP 5
We have multiplied by , and we want just by itself.
To get alone, we can divide *both* sides by :
Boom! We found the **magical value** of !
