For the last guy, our only choice is

We need a middle guy of 76x.

Which one of these will work?

( x 1 ) ( 7x 11 ) ... the inner terms give 7x and the outer terms give 11x ... we cannot get a 76x using 7x and 11x ... or ... ( x 11 ) ( 7x 1 ) ... the inner terms give 77x and the outer terms give x ... 77x - x = 76x ... the inside is positive and the outside is negative

So,
