Test 8 Section 3 #12

This one comes down to fraction manipulation. You’re asked for the value of . You’re given the value of , which is different from what you want in a couple ways. First, it has a 2 in it that you’ll need to get rid of. Second, it’s flipped. Luckily, we have operations available to us to resolve both of those differences!

Let’s get rid of the 2 first. To do so, we’ll multiply both sides of the given equation by .

Now we’re almost home. We know what equals, so all we need to do is flip it to find out what equals!
