2(4x+1)/5x-7 + 3(x-2)7-5x + -10x -1/5x-7

The answer in the book is-1. The closest I've come to getting that number is

5x -3/5x-7

But obviously that's not write and I had to do some pretty creative things to come up with that number. I'm pretty sure my error is happening when multiplying the middle term by -1 but still, I'm not getting the right answer. Any help is appreciated. Thanks.

P.S. If there's a way to more easily write out mathematical terms on the computer, I'd like to know about it.
