Confusing bind-off

I’m stumped! My pattern told me to knit until “armhole measures 7”. Then the next section is “Shape Shoulder”. Directions are as follows: Bind off 5 sts at armhole edge 3 times, then 6 sts 4 times. Bind off remaining 37 sts for back neck.

I’m unclear on where I am supposed to start the actual bind off. Ugh!:knitting:

Tart the bind off at the armhole edge. Every time you start a row at the armhole edge, bind off the given number of sts. So begin by binding off 5sts. The next time you are at the armhole edge and at the beginning of a row, bind off 5sts again and so on.
I’m not clear from the directions whether this is the back or one of the fronts of the sweater? Can you give us a link to the pattern or a pattern name?
