So This is probably +%283-x%29%2F%28%283x-1%29%28x%2B1%29%29+=+0+ Maybe it'd help if you rewrote it as

+%283-x%29%2F%28%283x-1%29%28x%2B1%29%29+=+0%2F1+ <---- and then cross-multiply. You'll then get

+3+-+x+=+0+ <--- just by looking at this equation, x = 3.

It seems almost stupid, but if you plug in 3 into the equation, you'll get a zero in the numerator. It won't matter what the denominator is because +0%2Fn+=+0+ just as long as that denominator n doesn't turn out to be 0.
